Merge branch 'bugfixes' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'bugfixes' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: SUNRPC: Fix use of static variable in rpcb_getport_async NFSv4.1: update nfs4_fattr_bitmap_maxsz SUNRPC: Fix a race between work-queue and rpc_killall_tasks pnfs: write: Set mds_offset in the generic layer - it is needed by all LDs
