ovl: make i_ino consistent with st_ino in more cases
Relax the condition that overlayfs supports nfs export, to require that i_ino is consistent with st_ino/d_ino. It is enough to require that st_ino and d_ino are consistent. This fixes the failure of xfstest generic/504, due to mismatch of st_ino to inode number in the output of /proc/locks. Fixes: 12574a9f4c9c ("ovl: consistent i_ino for non-samefs with xino") Cc: <stable@vger.kernel.org> # v4.19 Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
