Pull gpio updates from Bartosz Golaszewski:
 "The majority of added lines are two new modules: the GPIO virtual
  consumer module that improves our ability to add automated tests for
  the kernel API and the "sloppy" logic analyzer module that uses the
  GPIO API to implement a coarse-grained debugging tool for useful for
  remote development.

  Other than that we have the usual assortment of various driver
  extensions, improvements to the core GPIO code, DT-bindings and other
  documentation updates as well as an extension to the interrupt
  simulator:

  GPIOLIB core:
   - rework kfifo handling rework in the character device code
   - improve the labeling of GPIOs requested as interrupts and show more
     info on interrupt-only GPIOs in debugfs
   - remove unused APIs
   - unexport interfaces that are only used from the core GPIO code
   - drop the return value from gpiochip_set_desc_names() as it cannot
     fail
   - move a string array definition out of a header and into a specific
     compilation unit
   - convert the last user of gpiochip_get_desc() other than GPIO core
     to using a safer alternative
   - use array_index_nospec() where applicable

  New drivers:
   - add a "virtual GPIO consumer" module that allows requesting GPIOs
     from actual hardware and driving tests of the in-kernel GPIO API
     from user-space over debugfs
   - add a GPIO-based "sloppy" logic analyzer module useful for "first
     glance" debugging on remote boards

  Driver improvements:
   - add support for a new model to gpio-pca953x
   - lock GPIOs as interrupts in gpio-sim when the lines are requested
     as irqs via the simulator domain + some other minor improvements
   - improve error reporting in gpio-syscon
   - convert gpio-ath79 to using dynamic GPIO base and range
   - use pcibios_err_to_errno() for converting PCIBIOS error codes to
     errno vaues in gpio-amd8111 and gpio-rdc321x
   - allow building gpio-brcmstb for the BCM2835 architecture

  DT bindings:
   - convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
   - document new properties for aspeed,gpio, fsl,qoriq-gpio and
     gpio-vf610
   - document new compatibles for pca953x and fsl,qoriq-gpio

  Documentation:
   - document stricter behavior of the GPIO character device uAPI with
     regards to reconfiguring requested line without direction set
   - clarify the effect of the active-low flag on line values and edges
   - remove documentation for the legacy GPIO API in order to stop
     tempting people to use it
   - document the preference for using pread() for reading edge events
     in the sysfs API

  Other:
   - add an extended initializer to the interrupt simulator allowing to
     specify a number of callbacks callers can use to be notified about
     irqs being requested and released"

Pull power sequencing updates from Bartosz Golaszewski:
 "This has been in development since last year's Linux Plumbers
  Conference and was inspired by the need to enable support upstream for
  Bluetooth/WLAN chips on Qualcomm platforms.

  The main problem we're fixing is powering up devices which are
  represented as separate objects in the kernel (binding to different
  drivers) but which share parts of the power-up sequence and thus need
  some kind of a mediator who knows the possible interactions and can
  assure they don't interfere with neither device's bring up. An example
  of such an inter-driver interaction is the WCN family of BT/WLAN chips
  from Qualcomm of which some models require the user to observe a
  certain delay between driving the bt-enable and wlan-enable GPIOs.

  This is not a new problem but up to this point all attempts at
  addressing it ended up hitting one wall or another and being dropped.
  The main obstacle was the fact that most these attempts tried to
  introduce the concept of a "power sequence" into the device-tree
  bindings which breaks the main DT rule: describe the hardware, not its
  behavior. The solution I proposed focuses on making the power
  sequencer drivers interpret the actual HW description flexibly. More
  details on that are in the linked cover letter.

  The second problem fixed here is powering up PCI devices before they
  are detected on the bus. This is achieved by creating special platform
  devices for device-tree nodes describing hard-wired PCI devices which
  bind to the so-called PCI power control drivers which enable required
  resources and trigger a bus rescan once the controlled device is up
  then setup the correct devlink hierarchy for power-management.

  By combining the two new frameworks we implemented the power
  sequencing PCI power control driver which is capable of powering up
  the WLAN modules of the QCom WCN family of chipsets.

  All this has spent a significant amount of time in linux-next and
  enabled WLAN/BT support on several Qualcomm platforms. To further
  prove that this is useful and needed: right after this was picked up
  into next, I was sent a series using the subsystem for a similar
  use-case on Amlogic platforms.

  This contains the core power sequencing framework, the first driver,
  PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and
  some fixes that came later"

   - cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
     bits visible to guests

   - CPU errata: expand the speculative SSBS workaround to more CPUs

   - GICv3, use compile-time PMR values: optimise the way regular IRQs
     are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
     need for a static key in fast paths by using a priority value

creations and installations have been reworked based on wq_online_cpumask
rather than cpu_online_mask making cpus_read_lock() is unneeded during
wqattrs changes.

But it desn't remove the lockdep_assert_cpus_held() checks during wqattrs
changes, which leads to complaints from lockdep reported by kernel test

Fix it by removing the unneeded lockdep_assert_cpus_held().
Also remove the unneed cpus_read_lock() from wq_affn_dfl_set().

Pull workqueue updates from Tejun Heo:

 - Lai fixed a bug where CPU hotplug and workqueue attribute changes
   race leaving some workqueues not fully updated. This involved
   refactoring and changing how online CPUs are tracked. The resulting

 - Workqueue watchdog touch operation was causing too much cacheline
   contention on very large machines. Nicholas improved scalabililty by
   avoiding unnecessary global updates.

 - Code cleanups and minor rescuer behavior improvement.

 - The last commit 58629d48 ("workqueue: Always queue work items to

Pull pidfs updates from Christian Brauner:
 "This contains work to make it possible to derive namespace file
  descriptors from pidfd file descriptors.

  Right now it is already possible to use a pidfd with setns() to
  atomically change multiple namespaces at the same time. In other
  words, it is possible to switch to the namespace context of a process
  using a pidfd. There is no need to first open namespace file
  descriptors via procfs.

  The work included here is an extension of these abilities by allowing
  to open namespace file descriptors using a pidfd. This means it is now
  possible to interact with namespaces without ever touching procfs.

  To this end a new set of ioctls() on pidfds is introduced covering all
  supported namespace types"

  pidfs: allow retrieval of namespace file descriptors
  nsfs: add open_namespace()
  nsproxy: add helper to go from arbitrary namespace to ns_common
  nsproxy: add a cleanup helper for nsproxy
  file: add take_fd() cleanup helper

Pull namespace-fs updates from Christian Brauner:
 "This adds ioctls allowing to translate PIDs between PID namespaces.

  The motivating use-case comes from LXCFS which is a tiny fuse
  filesystem used to virtualize various aspects of procfs. LXCFS is run
  on the host. The files and directories it creates can be bind-mounted
  by e.g. a container at startup and mounted over the various procfs
  files the container wishes to have virtualized.

  When e.g. a read request for uptime is received, LXCFS will receive
  the pid of the reader. In order to virtualize the corresponding read,
  LXCFS needs to know the pid of the init process of the reader's pid
  namespace.

  In order to do this, LXCFS first needs to fork() two helper processes.
  The first helper process setns() to the readers pid namespace. The
  second helper process is needed to create a process that is a proper
  member of the pid namespace.

  The second helper process then creates a ucred message with ucred.pid
  set to 1 and sends it back to LXCFS. The kernel will translate the
  ucred.pid field to the corresponding pid number in LXCFS's pid
  namespace. This way LXCFS can learn the init pid number of the
  reader's pid namespace and can go on to virtualize.

  Since these two forks() are costly LXCFS maintains an init pid cache
  that caches a given pid for a fixed amount of time. The cache is
  pruned during new read requests. However, even with the cache the hit
  of the two forks() is singificant when a very large number of
  containers are running.

  So this adds a simple set of ioctls that let's a caller translate PIDs
  from and into a given PID namespace. This significantly improves
  performance with a very simple change.

  To protect against races pidfds can be used to check whether the
  process is still valid"

Pull vfs mount query updates from Christian Brauner:
 "This contains work to extend the abilities of listmount() and
  statmount() and various fixes and cleanups.

  Features:

   - Allow iterating through mounts via listmount() from newest to
     oldest. This makes it possible for mount(8) to keep iterating the
     mount table in reverse order so it gets newest mounts first.

   - Relax permissions on listmount() and statmount().

     It's not necessary to have capabilities in the initial namespace:
     it is sufficient to have capabilities in the owning namespace of
     the mount namespace we're located in to list unreachable mounts in
     that namespace.

   - Extend both listmount() and statmount() to list and stat mounts in
     foreign mount namespaces.

     Currently the only way to iterate over mount entries in mount
     namespaces that aren't in the caller's mount namespace is by
     crawling through /proc in order to find /proc/<pid>/mountinfo for
     the relevant mount namespace.

     This is both very clumsy and hugely inefficient. So extend struct
     mnt_id_req with a new member that allows to specify the mount
     namespace id of the mount namespace we want to look at.

     Luckily internally we already have most of the infrastructure for
     this so we just need to expose it to userspace. Give userspace a
     way to retrieve the id of a mount namespace via statmount() and
     through a new nsfs ioctl() on mount namespace file descriptor.

     This comes with appropriate selftests.

   - Expose mount options through statmount().

     Currently if userspace wants to get mount options for a mount and
     with statmount(), they still have to open /proc/<pid>/mountinfo to
     parse mount options. Simply the information through statmount()
     directly.

     Afterwards it's possible to only rely on statmount() and

Pull vfs inode / dentry updates from Christian Brauner:
 "This contains smaller performance improvements to inodes and dentries:

  inode:

   - Add rcu based inode lookup variants.

     They avoid one inode hash lock acquire in the common case thereby
     significantly reducing contention. We already support RCU-based
     operations but didn't take advantage of them during inode
     insertion.

     Callers of iget_locked() get the improvement without any code
     changes. Callers that need a custom callback can switch to
     iget5_locked_rcu() as e.g., did btrfs.

     With 20 threads each walking a dedicated 1000 dirs * 1000 files
     directory tree to stat(2) on a 32 core + 24GB ram vm:

        before: 3.54s user 892.30s system 1966% cpu 45.549 total
        after:  3.28s user 738.66s system 1955% cpu 37.932 total (-16.7%)

     Long-term we should pick up the effort to introduce more
     fine-grained locking and possibly improve on the currently used
     hash implementation.

   - Start zeroing i_state in inode_init_always() instead of doing it in
     individual filesystems.

     This allows us to remove an unneeded lock acquire in new_inode()
     and not burden individual filesystems with this.

  dcache:

   - Move d_lockref out of the area used by RCU lookup to avoid
     cacheline ping poing because the embedded name is sharing a
     cacheline with d_lockref.

   - Fix dentry size on 32bit with CONFIG_SMP=y so it does actually end
     up with 128 bytes in total"

Pull vfs mount API updates from Christian Brauner:

 - Add a generic helper to parse uid and gid mount options.

   Currently we open-code the same logic in various filesystems which is
   error prone, especially since the verification of uid and gid mount
   options is a sensitive operation in the face of idmappings.

   Add a generic helper and convert all filesystems over to it. Make
   sure that filesystems that are mountable in unprivileged containers
   verify that the specified uid and gid can be represented in the
   owning namespace of the filesystem.

 - Convert hostfs to the new mount api.

Pull misc vfs updates from Christian Brauner:
 "Features:

   - Support passing NULL along AT_EMPTY_PATH for statx().

     NULL paths with any flag value other than AT_EMPTY_PATH go the
     usual route and end up with -EFAULT to retain compatibility (Rust
     is abusing calls of the sort to detect availability of statx)

     This avoids path lookup code, lockref management, memory allocation
     and in case of NULL path userspace memory access (which can be
     quite expensive with SMAP on x86_64)

   - Don't block i_writecount during exec. Remove the
     deny_write_access() mechanism for executables

   - Relax open_by_handle_at() permissions in specific cases where we
     can prove that the caller had sufficient privileges to open a file

   - Switch timespec64 fields in struct inode to discrete integers
     freeing up 4 bytes

  Fixes:

   - Fix false positive circular locking warning in hfsplus

   - Initialize hfs_inode_info after hfs_alloc_inode() in hfs

   - Avoid accidental overflows in vfs_fallocate()

   - Don't interrupt fallocate with EINTR in tmpfs to avoid constantly
     restarting shmem_fallocate()

   - Add missing quote in comment in fs/readdir

  Cleanups:

   - Don't assign and test in an if statement in mqueue. Move the
     assignment out of the if statement

   - Reflow the logic in may_create_in_sticky()

   - Remove the usage of the deprecated ida_simple_xx() API from procfs

   - Reject FSCONFIG_CMD_CREATE_EXCL requets that depend on the new
     mount api early

   - Rename variables in copy_tree() to make it easier to understand

   - Replace WARN(down_read_trylock, ...) abuse with proper asserts in
     various places in the VFS

   - Get rid of user_path_at_empty() and drop the empty argument from
     getname_flags()

   - Check for error while copying and no path in one branch in
     getname_flags()

   - Avoid redundant smp_mb() for THP handling in do_dentry_open()

   - Rename parent_ino to d_parent_ino and make it use RCU

   - Remove unused header include in fs/readdir

   - Export in_group_capable() helper and switch f2fs and fuse over to

This is the last - for now - of the "look, we generated some
questionable code for basic pathname lookup operations" set of
branches.

This is mainly just re-organizing the name hashing code in
link_path_walk(), mostly by improving the calling conventions to
the inlined helper functions and moving some of the code around
to allow for more straightforward code generation.

The profiles - and the generated code - look much more palatable
to me now.
