Split DATA/NODE type bio cache according to different temperature, so write IOs with the same temperature can be merged in corresponding bio cache as much as possible, otherwise, different temperature write IOs submitting into one bio cache will always cause split of bio. Signed-off-by:

By default, f2fs_gc returns -EINVAL in general error cases, e.g., no victim was selected. However, the default errno may be overwritten in two cases: gc_more and BG_GC -> FG_GC. We should return consistent errno in such cases. Signed-off-by:

Last kernel has already support new syscall statx() in commit a528d35e ("statx: Add a system call to make enhanced file info available"), with this interface we can show more file info including file creation and some attribute flags to user. This patch tries to support this functionality. Signed-off-by:

Now that kref is using the refcount apis, the _GPL markings are getting exported to places that it previously wasn't. Now kref.h is GPLv2 licensed, so any non-GPL code using it better be talking to some lawyers, but changing api markings isn't considered "nice", so let's fix this up. Signed-off-by:

Since 2014, you can't successfully build kernels with GNU Make version 3.80. Example errors: $ git describe v4.11 $ make --version | head -1 GNU Make 3.80 $ make defconfig HOSTCC scripts/basic/fixdep scripts/Makefile.host:135: *** missing separator. Stop. make: *** [defconfig] Error 2 $ make ARCH=arm64 help arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'. Stop. $ make help >/dev/null ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional. Stop. make: *** [help] Error 2 The first breakage was introduced by commit c8589d1e ("kbuild: handle multi-objs dependency appropriately"). Since then (i.e. v3.18), GNU Make 3.80 has not been able to compile the kernel, but nobody has ever complained aboutt (or noticed) it. Even GNU Make 3.81 is more than 10 years old. It would not hurt to match the documentation with reality instead of fixing makefiles. Signed-off-by:

Pull libnvdimm updates from Dan Williams: "The bulk of this has been in multiple -next releases. There were a few late breaking fixes and small features that got added in the last couple days, but the whole set has received a build success notification from the kbuild robot. Change summary: - Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. - Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. - ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes. Acknowledgements that came after the branch was pushed: - commmit 565851c9 "device-dax: fix sysfs attribute deadlock": Tested-by:

Pull GFS2 updates from Bob Peterson: "We've got ten GFS2 patches for this merge window. - Andreas Gruenbacher wrote a patch to replace the deprecated call to rhashtable_walk_init with rhashtable_walk_enter. - Andreas also wrote a patch to eliminate redundant code in two of our debugfs sequence files. - Andreas also cleaned up the rhashtable key ugliness Linus pointed out during this cycle, following Linus's suggestions. - Andreas also wrote a patch to take advantage of his new function rhashtable_lookup_get_insert_fast. This makes glock lookup faster and more bullet-proof. - Andreas also wrote a patch to revert a patch in the evict path that caused occasional deadlocks, and is no longer needed. - Andrew Price wrote a patch to re-enable fallocate for the rindex system file to enable gfs2_grow to grow properly on secondary file system grow operations. - I wrote a patch to initialize an inode number field to make certain kernel trace points more understandable. - I also wrote a patch that makes GFS2 file system "withdraw" work more like it should by ignoring operations after a withdraw that would formerly cause a BUG() and kernel panic. - I also reworked the entire truncate/delete algorithm, scrapping the old recursive algorithm in favor of a new non-recursive algorithm. This was done for performance: This way, GFS2 no longer needs to lock multiple resource groups while doing truncates and deletes of files that cross multiple resource group boundaries, allowing for better parallelism. It also solves a problem whereby deleting large files would request a large chunk of kernel memory, which resulted in a get_page_from_freelist warning. - Due to a regression found during testing, I added a new patch to correct 'GFS2: Prevent BUG from occurring when normal Withdraws occur'." * tag 'gfs2-4.12.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: GFS2: Allow glocks to be unlocked after withdraw GFS2: Non-recursive delete gfs2: Re-enable fallocate for the rindex Revert "GFS2: Wait for iopen glock dequeues" gfs2: Switch to rhashtable_lookup_get_insert_fast GFS2: Temporarily zero i_no_addr when creating a dinode gfs2: Don't pack struct lm_lockname gfs2: Deduplicate gfs2_{glocks,glstats}_open gfs2: Replace rhashtable_walk_init with rhashtable_walk_enter GFS2: Prevent BUG from occurring when normal Withdraws occur

Pull orangefs updates from Mike Marshall: "Orangefs cleanups, fixes and statx support.

It has been posted to fs-devel during the previous rc period, we didn't get much review or feedback from there, but it has been reviewed very heavily here, so much so that we have two entire versions of the reimplementation. Not only does the new implementation fix some xfstests, but it passes all the new tests we made here that involve seeking and rewinding and giant directories and long file names.

This bug fixes a regression introduced by patch 0d1c7ae9. The intent of the patch was to stop promoting glocks after a file system is withdrawn due to a variety of errors, because doing so results in a BUG(). (You should be able to unmount after a withdraw rather than having the kernel panic.) Unfortunately, it also stopped demotions, so glocks could not be unlocked after withdraw, which means the unmount would hang. This patch allows function do_xmote to demote locks to an unlocked state after a withdraw, but not promote them. Signed-off-by:

Commit 28b783e4 ("xfs: bufferhead chains are invalid after end_page_writeback") fixed one use-after-free issue by pre-calculating the loop conditionals before calling bh->b_end_io() in the end_io processing loop, but it assigned 'next' pointer before checking end offset boundary & breaking the loop, at which point the bh might be freed already, and caused use-after-free. This is caught by KASAN when running fstests generic/127 on sub-page block size XFS.
