From: "Ritesh Harjani (IBM)" <ritesh.list@gmail.com> mainline inclusion from mainline-v6.15-rc4 commit 3be4bb7e71477c0b9708bd6f1975db0ffc72cce4 category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8862 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- This fixes the atomic write patch series after it was rebased on top of extent status cache cleanup series i.e. 'commit 402e38e6b71f57 ("ext4: prevent stale extent cache entries caused by concurrent I/O writeback")' After the above series, EXT4_GET_BLOCKS_IO_CONVERT_EXT flag which has EXT4_GET_BLOCKS_IO_SUBMIT flag set, requires that the io submit context of any kind should pass EXT4_EX_NOCACHE to avoid caching unncecessary extents in the extent status cache. This patch fixes that by adding the EXT4_EX_NOCACHE flag in ext4_convert_unwritten_extents_atomic() for unwritten to written conversion calls to ext4_map_blocks().
