udf_process_sequence() allocates temporary array for processing partition descriptors on volume which it fails to free. Free the array when it is not needed anymore.

unlock_new_inode() is only meant to be called after a new inode has already been inserted into the hash table. But reiserfs_new_inode() can call it even before it has inserted the inode, triggering the WARNING in unlock_new_inode(). Fix this by only calling unlock_new_inode() if the inode has the I_NEW flag set, indicating that it's in the table. This addresses the syzbot report "WARNING in unlock_new_inode" (https://syzkaller.appspot.com/bug?extid=187510916eb6a14598f7).

Soon, XFS will support quota grace period expiration timestamps beyond the year 2038, widen the timestamp fields to handle the extra time bits. Internally, XFS now stores unsigned 34-bit quantities, so the extra 8 bits here should work fine. (Note that XFS is the only user of this structure.)

Merge tag 'fallthrough-pseudo-keyword-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux Pull 'fallthrough' keyword conversion from Gustavo A. R. Silva: "A tree-wide patch that replaces tons (2484) of /* fall through */ comments, and its variants, with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case. There are currently 1167 intances of this fallthrough pseudo-keyword macro in mainline (5.9-rc2), that have been introduced over the last couple of development cycles: $ git grep -nw 'fallthrough;' | wc -l 1167 The global adoption of the fallthrough pseudo-keyword is something certain to happen; so, better sooner than later. :) This will also save everybody's time and thousands of lines of unnecessarily repetitive changelog text. After applying this patch on top of 5.9-rc2, we'll have a total of 3651 instances of this macro: $ git grep -nw 'fallthrough;' | wc -l 3651 This treewide patch doesn't address ALL fall-through markings in all subsystems at once because I have previously sent out patches for some of such subsystems separately, and I will follow up on them; however, this definitely contributes most of the work needed to replace all the fall-through markings with the fallthrough pseudo-keyword macro in the whole codebase. I have build-tested this patch on 10 different architectures: x86_64, i386, arm64, powerpc, s390, sparc64, sh, m68k, powerpc64 and alpha (allyesconfig for all of them).

Pull x86 fix from Thomas Gleixner: "A single fix for x86 which removes the RDPID usage from the paranoid entry path and unconditionally uses LSL to retrieve the CPU number. RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values and restores them either when leaving the run loop, on preemption or when going out to user space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest value and before the lazy restore any exception using the paranoid entry will read the guest value and use it as CPU number to retrieve the GSBASE value for the current CPU when FSGSBASE is enabled. As RDPID is only used in that particular entry path, there is no reason to burden VMENTER/EXIT with two extra MSR writes. Remove the RDPID optimization, which is not even backed by numbers from the paranoid entry path instead" * tag 'x86-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Do not use RDPID in paranoid entry to accomodate KVM

When adding a new fd to an epoll, and that this new fd is an epoll fd itself, we recursively scan the fds attached to it to detect cycles, and add non-epool files to a "check list" that gets subsequently parsed. However, this check list isn't completely safe when deletions can happen concurrently. To sidestep the issue, make sure that a struct file placed on the check list sees its f_count increased, ensuring that a concurrent deletion won't result in the file disapearing from under our feet.

Currently the nexthop code will use an empty NHA_GROUP attribute, but it requires at least 1 entry in order to function properly. Otherwise we end up derefencing null or random pointers all over the place due to not having any nh_grp_entry members allocated, nexthop code relies on having at least the first member present. Empty NHA_GROUP doesn't make any sense so just disallow it. Also add a WARN_ON for any future users of nexthop_create_group().

Pull arm64 fixes from Catalin Marinas: - Allow booting of late secondary CPUs affected by erratum 1418040 (currently they are parked if none of the early CPUs are affected by this erratum). - Add the 32-bit vdso Makefile to the vdso_install rule so that 'make vdso_install' installs the 32-bit compat vdso when it is compiled. - Print a warning that untrusted guests without a CPU erratum workaround (Cortex-A57 832075) may deadlock the affected system. * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: ARM64: vdso32: Install vdso32 from vdso_install KVM: arm64: Print warning when cpu erratum can cause guests to deadlock arm64: Allow booting of late CPUs affected by erratum 1418040 arm64: Move handling of erratum 1418040 into C code

Check the SCT sub-field for a path related status instead of enumerating invididual status code. As of NVMe 1.4 this adds "Internal Path Error" and "Controller Pathing Error" to the list, but it also future proofs for additional status codes added to the category.

Lift all the code to decide the dispostition of a completed command from nvme_complete_rq and nvme_failover_req into a new helper, which returns an emum of the potential actions. nvme_complete_rq then just switches on those and calls the proper helper for the action.

nvme_end_request is a bit misnamed, as it wraps around the blk_mq_complete_* API. It's semantics also are non-trivial, so give it a more descriptive name and add a comment explaining the semantics.

Zoned block devices reuse the chunk_sectors queue limit to define zone boundaries. If a such a device happens to also report an optimal boundary, do not use that to define the chunk_sectors as that may intermittently interfere with io splitting and zone size queries.
