commit370345b4bdupstream. RFC 8881 Section 18.25.4 paragraph 5 tells us that the server should return NFS4ERR_FILE_OPEN only if the target object is an opened file. This suggests that returning this status when removing a directory will confuse NFS clients. This is a version-specific issue; nfsd_proc_remove/rmdir() and nfsd3_proc_remove/rmdir() already return nfserr_access as appropriate. Unfortunately there is no quick way for nfsd4_remove() to determine whether the target object is a file or not, so the check is done in in nfsd_unlink() for now.
