Merge branch 'for-3.9' of git://linux-nfs.org/~bfields/linux
Pull nfsd bugfixes from Bruce Fields: "Some minor fallout from the user-namespace work broke most krb5 mounts to nfsd, and I screwed up a change to the AF_LOCAL rpc code." * 'for-3.9' of git://linux-nfs.org/~bfields/linux: sunrpc: don't attempt to cancel unitialized work nfsd: fix krb5 handling of anonymous principals
