I originally reported this last year (https://lore.kernel.org/r/20200306004555.GB225345@gmail.com) because it causes the FS_IOC_REMOVE_ENCRYPTION_KEY ioctl to not work properly, as the bug causes inodes to remain dirty after a sync. It also turns out that lazytime on XFS is partially broken because it doesn't actually write timestamps to disk after a sync() or after dirtytime_expire_interval. This is fixed by the same fix. This supersedes previously proposed fixes, including https://lore.kernel.org/r/20200307020043.60118-1-tytso@mit.edu and https://lore.kernel.org/r/20200325122825.1086872-3-hch@lst.de from last year (which had some issues and didn't fix the XFS bug), and v1 of this patchset which took a different approach (https://lore.kernel.org/r/20210105005452.92521-1-ebiggers@kernel.org). Patches 2-11 then clean up various things related to lazytime and writeback, such as clarifying the semantics of ->dirty_inode() and the inode dirty flags, and improving comments. This patchset applies to v5.11-rc2. Changed v2 => v3: - Changed ext4 patch to add a helper function inode_is_dirtytime_only() to include/linux/fs.h. - Dropped XFS cleanup patch, as it can be sent/applied separately. - Added Reviewed-by's. Changed v1 => v2: - Switched to the fix suggested by Jan Kara, and dropped the patches which introduced ->lazytime_expired(). - Fixed bugs in the fat and ext4 patches. - Added patch "fs: improve comments for writeback_single_inode()". - Reordered the patches a bit. - Added Reviewed-by's. Eric Biggers (11): fs: fix lazytime expiration handling in __writeback_single_inode() fs: correctly document the inode dirty flags fs: only specify I_DIRTY_TIME when needed in generic_update_time() fat: only specify I_DIRTY_TIME when needed in fat_update_time() fs: don't call ->dirty_inode for lazytime timestamp updates fs: pass only I_DIRTY_INODE flags to ->dirty_inode fs: clean up __mark_inode_dirty() a bit fs: drop redundant check from __writeback_single_inode() fs: improve comments for writeback_single_inode() gfs2: don't worry about I_DIRTY_TIME in gfs2_fsync() ext4: simplify i_state checks in __ext4_update_other_inode_time() Documentation/filesystems/vfs.rst | 5 +- fs/ext4/inode.c | 20 +---- fs/f2fs/super.c | 3 - fs/fat/misc.c | 23 +++--- fs/fs-writeback.c | 132 +++++++++++++++++------------- fs/gfs2/file.c | 4 +- fs/gfs2/super.c | 2 - fs/inode.c | 38 +++++---- include/linux/fs.h | 33 ++++++-- 9 files changed, 146 insertions(+), 114 deletions(-) base-commit: e71ba9452f0b5b2e8dc8aa5445198cd9214a6a62 -- 2.30.0
