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

It's already into 6.6 and fixes the Syzkaller issue Link: https://syzkaller.appspot.com/bug?id=e4aaa78795e490421c79f76ec3679006c8ff4cf... 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.
