[lvc-project] [PATCH 5.15 0/1] ext4, jbd2: add an optimized bmap for the journal inode

[Nikolay Kuratov]

It's already into 6.6 and fixes the Syzkaller issue
Link: https://syzkaller.appspot.com/bug?id=e4aaa78795e490421c79f76ec3679006c8ff4cf0
Theoretically the issue boils down to
commit 51ae846cff56 ("ext4: fix warning in ext4_iomap_begin
as race between bmap and write")
so it should be in 5.10, 5.15 and 6.1 kernels.
But we at Linux Verification Center can reproduce it with 5.15 and 6.1 only
so I'm asking to apply the fix for those two.
