--- Comment #3 from Eric Sandeen (sandeen@...deen.net) ---
I don't think 1s is considered a hang, it's just doing a slower traversal of a
corrupt directory.

The nonstandard error code is incorrect though, I've sent a patch upstream for
that.

[PATCH] ext4: Reset error code in ext4_find_entry in fallback

When ext4_find_entry() falls back to "searching the old fashioned
way" due to a corrupt dx dir, it needs to reset the error code
to NULL so that the nonstandard ERR_BAD_DX_DIR code isn't returned
to userspace.
