J. Bruce Fields a4f4d6df53 EXPORTFS: handle NULL returns from fh_to_dentry()/fh_to_parent() ... While 440037287c "[PATCH] switch all filesystems over to d_obtain_alias" removed some cases where fh_to_dentry() and fh_to_parent() could return NULL, there are still a few NULL returns left in individual filesystems. Thus it was a mistake for that commit to remove the handling of NULL returns in the callers. Revert those parts of 440037287c which removed the NULL handling. (We could, alternatively, modify all implementations to return -ESTALE instead of NULL, but that proves to require fixing a number of filesystems, and in some cases it's arguably more natural to return NULL.) Thanks to David for original patch and Linus, Christoph, and Hugh for review. Signed-off-by: J.
