"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: always drain queued discard work in ext4_mb_release()\n\nWhile reviewing recent ext4 patch[1], Sashiko raised the following\nconcern[2]:\n\n> If the filesystem is initially mounted with the discard option,\n> deleting files will populate sbi->s_discard_list and queue\n> s_discard_work. If it is then remounted with nodiscard, the\n> EXT4_MOUNT_DISCARD flag is cleared, but the pending s_discard_work is\n> neither cancelled nor flushed.\n\n[1] https://lore.kernel.org/r/20260319094545.19291-1-qiang.zhang@linux.dev/\n[2] https://sashiko.dev/#/patchset/20260319094545.19291-1-qiang.zhang%40linux.dev\n\nThe concern was valid, but it had nothing to do with the patch[1].\nOne of the problems with Sashiko in its current (early) form is that\nit will detect pre-existing issues and report it as a problem with the\npatch that it is reviewing.\n\nIn practice, it would be hard to hit deliberately (unless you are a\nmalicious syzkaller fuzzer), since it would involve mounting the file\nsystem with -o discard, and then deleting a large number of files,\nremounting the file system with -o nodiscard, and then immediately\nunmounting the file system before the queued discard work has a change\nto drain on its own.\n\nFix it because it's a real bug, and to avoid Sashiko from raising this\nconcern when analyzing future patches to mballoc.c."
