Merge git://git.linux-nfs.org/pub/linux/nfs-2.6
* git://git.linux-nfs.org/pub/linux/nfs-2.6: (103 commits) SUNRPC,RPCSEC_GSS: spkm3--fix config dependencies SUNRPC,RPCSEC_GSS: spkm3: import contexts using NID_cast5_cbc LOCKD: Make nlmsvc_traverse_shares return void LOCKD: nlmsvc_traverse_blocks return is unused SUNRPC,RPCSEC_GSS: fix krb5 sequence numbers. NFSv4: Dont list system.nfs4_acl for filesystems that don't support it. SUNRPC,RPCSEC_GSS: remove unnecessary kmalloc of a checksum SUNRPC: Ensure rpc_call_async() always calls tk_ops->rpc_release() SUNRPC: Fix memory barriers for req->rq_received NFS: Fix a race in nfs_sync_inode() NFS: Clean up nfs_flush_list() NFS: Fix a race with PG_private and nfs_release_page() NFSv4: Ensure the callback daemon flushes signals SUNRPC: Fix a 'Busy inodes' error in rpc_pipefs NFS, NLM: Allow blocking locks to respect signals NFS: Make nfs_fhget() return appropriate error values NFSv4: Fix an oops in nfs4_fill_super lockd: blocks should hold a reference to the nlm_file NFSv4: SETCLIENTID_CONFIRM should handle NFS4ERR_DELAY/NFS4ERR_RESOURCE NFSv4: Send the delegation stateid for SETATTR calls ...
