NLM: nlm_lookup_file() may return NLMv4-specific error codes
commit cd0b16c1c3cda12dbed1f8de8f1a9b0591990724 upstream. If the filehandle is stale, or open access is denied for some reason, nlm_fopen() may return one of the NLMv4-specific error codes nlm4_stale_fh or nlm4_failed. These get passed right through nlm_lookup_file(), and so when nlmsvc_retrieve_args() calls the latter, it needs to filter the result through the cast_status() machinery. Failure to do so, will trigger the BUG_ON() in encode_nlm_stat... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Reported-by: Larry McVoy <lm@bitmover.com> Signed-off-by: J.
