Pull nfsd fixes from Bruce Fields:
"A couple minor fixes for the (new to 3.10) gss-proxy code.
And one regression from user-namespace changes. (XBMC clients were
doing something admittedly weird--sending -1 gid's--but something that
we used to allow.)"
* 'for-3.10' of git://linux-nfs.org/~bfields/linux:
svcrpc: fix failures to handle -1 uid's and gid's
svcrpc: implement O_NONBLOCK behavior for use-gss-proxy
svcauth_gss: fix error code in use_gss_proxy()
