Pull NFS client bugfixes from Trond Myklebust: "We've just concluded another Connectathon interoperability testing week, and so here are the fixes for the bugs that were discovered: - Don't allow NFS silly-renamed files to be deleted - Don't start the retransmission timer when out of socket space - Fix a couple of pnfs-related Oopses. - Fix one more NFSv4 state recovery deadlock - Don't loop forever when LAYOUTGET returns NFS4ERR_LAYOUTTRYLATER" * tag 'nfs-for-3.9-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: SUNRPC: One line comment fix NFSv4.1: LAYOUTGET EDELAY loops timeout to the MDS SUNRPC: add call to get configured timeout PNFS: set the default DS timeout to 60 seconds NFSv4: Fix another open/open_recovery deadlock nfs: don't allow nfs_find_actor to match inodes of the wrong type NFSv4.1: Hold reference to layout hdr in layoutget pnfs: fix resend_to_mds for directio SUNRPC: Don't start the retransmission timer when out of socket space NFS: Don't allow NFS silly-renamed files to be deleted, no signal
