As Eric reported:
RENAME_EXCHANGE support was just added to fsstress in xfstests:
commit 65dfd40a97b6bbbd2a22538977bab355c5bc0f06
Author: kaixuxia <xiakaixu1987@gmail.com>

fsstress: add EXCHANGE renameat2 support
This is causing xfstest generic/579 to fail due to fsck.f2fs reporting errors.
I'm not sure what the problem is, but it still happens even with all the
fs-verity stuff in the test commented out, so that the test just runs fsstress.

Here's the contents of 579.full:

The root cause is that we forgot to update directory's i_pino during
cross_rename, fix it.

The i_pino field is only valid on directories, right?

Thanks for the test.

i_pino is also valid on regular inode, because after sudden power-cut case, we
will recover fsynced file and link it into parent directory which i_pino field
points.
For rename/cross_rename cases, we just tag src/dst regular inode with
parent_lost flag instead of updating its i_pino field, once there is fsync()
comes after rename(), we will trigger checkpoint for such parent lost inode to
keep rename/cross_rename operation as an atomic operation.
