Hi Linus, Could you please consider this pull request?
Thanks as always, The following changes since commit 8ab774587903771821b59471cc723bba6d893942: Merge tag 'trace-v5.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace (2021-11-14 19:07:19 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs.git tags/f2fs-for-5.17-rc1 for you to fetch changes up to 5fed0be8583f08c1548b4dcd9e5ee0d1133d0730: f2fs: do not allow partial truncation on pinned file (2022-01-10 09:05:09 -0800) ---------------------------------------------------------------- f2fs-for-5.17-rc1 In this round, we've tried to address some performance issues in f2fs_checkpoint and direct IO flows. Also, there was a work to enhance the page cache management used for compression. Other than them, we've done typical work including sysfs, code clean-ups, tracepoint, sanity check, in addition to bug fixes on corner cases. Enhancement: - use iomap for direct IO - try to avoid lock contention to improve f2fs_ckpt speed - avoid unnecessary memory allocation in compression flow - POSIX_FADV_DONTNEED drops the page cache containing compression pages - add some sysfs entries (gc_urgent_high_remaining, pending_discard) Bug fix: - try not to expose unwritten blocks to user by DIO : this was added to avoid merge conflict; another patch is coming to address other missing case. - relax minor error condition for file pinning feature used in Android OTA - fix potential deadlock case in compression flow - should not truncate any block on pinned file In addition, we've done some code clean-ups and tracepoint/sanity check improvement. ---------------------------------------------------------------- Chao Yu (9): f2fs: fix to do sanity check on inode type during garbage collection f2fs: fix to avoid panic in is_alive() if metadata is inconsistent f2fs: fix to do sanity check in is_alive() f2fs: fix to do sanity check on last xattr entry in __f2fs_setxattr() f2fs: clean up __find_inline_xattr() with __find_xattr() f2fs: support fault injection to f2fs_trylock_op() f2fs: fix to check available space of CP area correctly in update_ckpt_flags() f2fs: fix to reserve space for IO align feature f2fs: don't drop compressed page cache in .{invalidate,release}page Daeho Jeong (1): f2fs: add gc_urgent_high_remaining sysfs node Eric Biggers (5): f2fs: rework write preallocations f2fs: reduce indentation in f2fs_file_write_iter() f2fs: fix the f2fs_file_write_iter tracepoint f2fs: implement iomap operations f2fs: use iomap for direct I/O Fengnan Chang (4): f2fs: compress: reduce one page array alloc and free when write compressed page f2fs: fix remove page failed in invalidate compress pages f2fs: support POSIX_FADV_DONTNEED drop compressed page cache f2fs: remove redunant invalidate compress pages Hyeong-Jun Kim (1): f2fs: compress: fix potential deadlock of compress file Jaegeuk Kim (8): f2fs: do not expose unwritten blocks to user by DIO f2fs: show more DIO information in tracepoint f2fs: show number of pending discard commands f2fs: avoid duplicate call of mark_inode_dirty f2fs: avoid EINVAL by SBI_NEED_FSCK when pinning a file f2fs: avoid down_write on nat_tree_lock during checkpoint f2fs: do not bother checkpoint by f2fs_get_node_info f2fs: do not allow partial truncation on pinned file Yang Li (1): f2fs: Simplify bool conversion Documentation/ABI/testing/sysfs-fs-f2fs | 12 + Documentation/filesystems/f2fs.rst | 1 + fs/f2fs/Kconfig | 1 + fs/f2fs/checkpoint.c | 6 +- fs/f2fs/compress.c | 84 +++--- fs/f2fs/data.c | 351 +++++----------------- fs/f2fs/f2fs.h | 43 ++- fs/f2fs/file.c | 509 ++++++++++++++++++++++++++------ fs/f2fs/gc.c | 26 +- fs/f2fs/inline.c | 4 +- fs/f2fs/inode.c | 18 +- fs/f2fs/iostat.c | 40 ++- fs/f2fs/node.c | 23 +- fs/f2fs/recovery.c | 2 +- fs/f2fs/segment.c | 2 +- fs/f2fs/segment.h | 3 +- fs/f2fs/super.c | 46 +++ fs/f2fs/sysfs.c | 26 +- fs/f2fs/xattr.c | 40 +-- include/trace/events/f2fs.h | 27 +- 20 files changed, 759 insertions(+), 505 deletions(-) _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
