When changing the size of a block device, its all caches are freed. It's necessary on shrinking to prevent spurious I/Os to the disappeared region. However, on expanding, such kind of I/Os doesn't happen. Similar things can be considered for btrfs filesystem resize and resize2fs, but they are designed not to drop caches when expanding. Therefore this patch removes unnecessary cache drop. Link: http://lkml.kernel.org/r/1521457240-153390-1-git-send-email-shunki-fujita@cybozu.co.jpSigned-off-by:

When specifying trans_mod multiple times in a mount, it will cause an inaccurate refcount of the trans module. Also, in the error case of option parsing, we should put the trans module if we have already got it. Link: http://lkml.kernel.org/r/1522154942-57339-1-git-send-email-cgxu519@gmx.comSigned-off-by:

When the user uses some syscall, for example mmap(v9fs_file_mmap), it will not update atime even if user's was set mnt_flags without MNT_NOATIME, because v9fs defaults to settine SB_NOATIME in v9fs_set_super. For supporting access time updating when the user mounts with relatime, we should not set SB_NOATIME by default. Link: http://lkml.kernel.org/r/5AB9A377.6080906@huawei.comSigned-off-by:

If the exported filesystem dir on 9p server doesn't maintain accurate i_nlink count, e.g. always reports i_nlink as 1, then 9p should not maintain nlink count either, otherwise drop_link would report warning with i_nlink being zero. For example: - overlayfs sets nlink to 1 for merged dir - ext4 (with dir_nlink feature enabled) sets nlink to 1 if a dir has more than EXT4_LINK_MAX (65000) links. In this case, everytime a stat(2) call (getattr) on such exported dirs on 9p client side, the i_nlink gets reset to 1, then operations like rmdir(2), unlink(2) and rename(2) would cause the dir nlink to go to zero (then negative), which results in warnings in drop_nlink() and/or inc_nlink() calls. This can be reproduced easily as the following steps: - export a merged overlayfs dir via qemu virtfs to guest - mount the exported virtfs in guest - create two sub-directories in the root dir of the mounted 9pfs - stat the root dir of 9pfs, this resets nlink to 1 - remove all subdirs, the second unlink/rmdir would trigger warning ------------[ cut here ]------------ WARNING: CPU: 3 PID: 1284 at fs/inode.c:282 drop_nlink+0x3e/0x50 ...

If it was interrupted by a signal, the 9p client may need to send some more requests to the server for cleanup before returning to userspace. To avoid such a last minute request to be interrupted right away, the client memorizes if a signal is pending, clears TIF_SIGPENDING, handles the request and calls recalc_sigpending() before returning. Unfortunately, if the transmission of this cleanup request fails for any reason, the transport returns an error and the client propagates it right away, without calling recalc_sigpending(). This ends up with -ERESTARTSYS from the initially interrupted request crawling up to syscall exit, with TIF_SIGPENDING cleared by the cleanup request. The specific signal handling code, which is responsible for converting -ERESTARTSYS to -EINTR is not called, and userspace receives the confusing errno value: open: Unknown error 512 (512) This is really hard to hit in real life. I discovered the issue while working on hot-unplug of a virtio-9p-pci device with an instrumented QEMU allowing to control request completion. Both p9_client_zc_rpc() and p9_client_rpc() functions have this buggy error path actually. Their code flow is a bit obscure and the best thing to do would probably be a full rewrite: to really ensure this situation of clearing TIF_SIGPENDING and returning -ERESTARTSYS can never happen. But given the general lack of interest for the 9p code, I won't risk breaking more things. So this patch simply fixes the buggy paths in both functions with a trivial label+goto. Thanks to Laurent Dufour for his help and suggestions on how to find the root cause and how to fix it.

Patch series "ocfs2: use kobject for online file check", v3. Use embedded kobject mechanism for online file check feature, this will avoid to use a global list to save/search per-device online file check related data. The changed code is based on Goldwyn Rodrigues's patches and ext4 fs code, there is not any new features added, except some very small fixes during this code refactoring. Second, the code change does not affect the underlying file check code. Thank Goldwyn very much. Compare with second version, add more comments in the patch descriptions, to make sure each modification is mentioned. Compare with first version, split the code change into four patches, make sure each patch will not bring ocfs2 kernel modules compiling errors. This patch (of 3): Move some definitions to header file, which will be referenced by other source files when kobject mechanism is introduced.

We should not handle migrate lockres if we are already in 'DLM_CTXT_IN_SHUTDOWN', as that will cause lockres remains after leaving dlm domain. At last other nodes will get stuck into infinite loop when requsting lock from us. The problem is caused by concurrency umount between nodes. Before receiveing N1's DLM_BEGIN_EXIT_DOMAIN_MSG, N2 has picked up N1 as the migrate target. So N2 will continue sending lockres to N1 even though N1 has left domain. N1 N2 (owner) touch file access the file, and get pr lock begin leave domain and pick up N1 as new owner begin leave domain and migrate all lockres done begin migrate lockres to N1 end leave domain, but the lockres left unexpectedly, because migrate task has passed [piaojun@huawei.com: v3] Link: http://lkml.kernel.org/r/5A9CBD19.5020107@huawei.com Link: http://lkml.kernel.org/r/5A99F028.2090902@huawei.comSigned-off-by: -

This is a fix for a regression in 32 bit kernels caused by an invalid check for pgoff overflow in hugetlbfs mmap setup. The check incorrectly specified that the size of a loff_t was the same as the size of a long. The regression prevents mapping hugetlbfs files at offsets greater than 4GB on 32 bit kernels. On 32 bit kernels conversion from a page based unsigned long can not overflow a loff_t byte offset. Therefore, skip this check if sizeof(unsigned long) != sizeof(loff_t).

Calling __stack_chk_guard_setup() in decompress_kernel() is too late that stack checking always fails for decompress_kernel() itself. So remove __stack_chk_guard_setup() and initialize __stack_chk_guard before we call decompress_kernel(). Original code comes from ARM but also used for MIPS and SH, so fix them together. If without this fix, compressed booting of these archs will fail because stack checking is enabled by default (>=4.16).

Pull tty/serial driver updates from Greg KH: "Here is the big set of tty and serial driver patches for 4.17-rc1 Not all that big really, most are just small fixes and additions to existing drivers.

Pull USB/PHY updates from Greg KH: "Here is the big set of USB and PHY driver patches for 4.17-rc1. Lots of USB typeC work happened this round, with code moving from the staging directory into the "real" part of the kernel, as well as new infrastructure being added to be able to handle the different types of "roles" that typeC requires. There is also the normal huge set of USB gadget controller and driver updates, along with XHCI changes, and a raft of other tiny fixes all over the USB tree. And the PHY driver updates are merged in here as well as they interacted with the USB drivers in some places.

Pull networking fixes from David Miller: "This fixes some fallout from the net-next merge the other day, plus some non-merge-window-related bug fixes: 1) Fix sparse warnings in bcmgenet, systemport, b53, and mt7530 (Florian Fainelli) 2) pptp does a bogus dst_release() on a route we have a single refcount on, and attached to a socket, which needs that refcount (Eric Dumazet) 3) UDP connected sockets on ipv6 can race with route update handling, resulting in a pre-PMTU update route still stuck on the socket and thus continuing to get ICMPV6_PKT_TOOBIG errors. We end up never seeing the updated route.

Merge tag 'riscv-for-linus-4.17-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains the new features we'd like to incorporate into the RISC-V port for 4.17. We might have a bit more stuff land later in the merge window, but I wanted to get this out earlier just so everyone can see where we currently stand. A short summary of the changes is: - We've added support for dynamic ftrace on RISC-V targets. - There have been a handful of cleanups to our atomic and locking routines. They now more closely match the released RISC-V memory model draft. - Our module loading support has been cleaned up and is now enabled by default, despite some limitations still existing. - A patch to define COMMANDLINE_FORCE instead of COMMANDLINE_OVERRIDE so the generic device tree code picks up handling all our command line stuff.

Pull arm64 updates from Will Deacon: "Nothing particularly stands out here, probably because people were tied up with spectre/meltdown stuff last time around. Still, the main pieces are: - Rework of our CPU features framework so that we can whitelist CPUs that don't require kpti even in a heterogeneous system - Support for the IDC/DIC architecture extensions, which allow us to elide instruction and data cache maintenance when writing out instructions - Removal of the large memory model which resulted in suboptimal codegen by the compiler and increased the use of literal pools, which could potentially be used as ROP gadgets since they are mapped as executable - Rework of forced signal delivery so that the siginfo_t is well-formed and handling of show_unhandled_signals is consolidated and made consistent between different fault types - More siginfo cleanup based on the initial patches from Eric Biederman - Workaround for Cortex-A55 erratum #1024718 - Some small ACPI IORT updates and cleanups from Lorenzo Pieralisi - Misc cleanups and non-critical fixes" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (70 commits) arm64: uaccess: Fix omissions from usercopy whitelist arm64: fpsimd: Split cpu field out from struct fpsimd_state arm64: tlbflush: avoid writing RES0 bits arm64: cmpxchg: Include linux/compiler.h in asm/cmpxchg.h arm64: move percpu cmpxchg implementation from cmpxchg.h to percpu.h arm64: cmpxchg: Include build_bug.h instead of bug.h for BUILD_BUG arm64: lse: Include compiler_types.h and export.h for out-of-line LL/SC arm64: fpsimd: include <linux/init.h> in fpsimd.h drivers/perf: arm_pmu_platform: do not warn about affinity on uniprocessor perf: arm_spe: include linux/vmalloc.h for vmap() Revert "arm64: Revert L1_CACHE_SHIFT back to 6 (64-byte cache line size)" arm64: cpufeature: Avoid warnings due to unused symbols arm64: Add work around for Arm Cortex-A55 Erratum 1024718 arm64: Delay enabling hardware DBM feature arm64: Add MIDR encoding for Arm Cortex-A55 and Cortex-A35 arm64: capabilities: Handle shared entries arm64: capabilities: Add support for checks based on a list of MIDRs arm64: Add helpers for checking CPU MIDR against a range arm64: capabilities: Clean up midr range helpers arm64: capabilities: Change scope of VHE to Boot CPU feature ... -
