Subject: Re: [Android 5.10] kernel BUG in ext4_free_blocks (2)

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 the tested trees[1] 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.
