| |
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Weston Andros Adamson <dros@primarydata.com>
commit 78b19bae0813bd6f921ca58490196abd101297bd upstream.
Don't check for -NFS4ERR_NOTSUPP, it's already been mapped to -ENOTSUPP by nfs4_stat_to_errno.
This allows the client to mount v4.1 servers that don't support SECINFO_NO_NAME by falling back to the "guess and check" method of nfs4_find_root_sec.
