This bug is marked as fixed by commit: ext4: block range must be validated before use in ext4_mb_clear_bb() But I can't find it in any tested tree for more than 90 days. Is it a correct commit? Please update it by replying: #syz fix: exact-commit-title Until then the bug is still considered open and new crashes with the same signature are ignored.
I don't know what is going on with syzkaller's commit detection, but commit 1e1c2b86ef86 ("ext4: block range must be validated before use in ext4_mb_clear_bb()") is an exact match for the commit title, and it's been in the upstream kernel since v6.0.
How do we make syzkaller accept this? I'll try this again, but I don't hold out much hope.

Syzkaller, go home, you're drunk.
