Merge branch 'for-3.11' of git://linux-nfs.org/~bfields/linux

Pull nfsd changes from Bruce Fields:
 "Changes this time include:

   - 4.1 enabled on the server by default: the last 4.1-specific issues
     I know of are fixed, so we're not going to find the rest of the
     bugs without more exposure.
   - Experimental support for NFSv4.2 MAC Labeling (to allow running
     selinux over NFS), from Dave Quigley.
   - Fixes for some delicate cache/upcall races that could cause rare
     server hangs; thanks to Neil Brown and Bodo Stroesser for extreme
     debugging persistence.
   - Fixes for some bugs found at the recent NFS bakeathon, mostly v4
     and v4.1-specific, but also a generic bug handling fragmented rpc
     calls"
