Merge branch 'nfs-for-2.6.35' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'nfs-for-2.6.35' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (78 commits) SUNRPC: Don't spam gssd with upcall requests when the kerberos key expired SUNRPC: Reorder the struct rpc_task fields SUNRPC: Remove the 'tk_magic' debugging field SUNRPC: Move the task->tk_bytes_sent and tk_rtt to struct rpc_rqst NFS: Don't call iput() in nfs_access_cache_shrinker NFS: Clean up nfs_access_zap_cache() NFS: Don't run nfs_access_cache_shrinker() when the mask is GFP_NOFS SUNRPC: Ensure rpcauth_prune_expired() respects the nr_to_scan parameter SUNRPC: Ensure memory shrinker doesn't waste time in rpcauth_prune_expired() SUNRPC: Dont run rpcauth_cache_shrinker() when gfp_mask is GFP_NOFS NFS: Read requests can use GFP_KERNEL. NFS: Clean up nfs_create_request() NFS: Don't use GFP_KERNEL in rpcsec_gss downcalls NFSv4: Don't use GFP_KERNEL allocations in state recovery SUNRPC: Fix xs_setup_bc_tcp() SUNRPC: Replace jiffies-based metrics with ktime-based metrics ktime: introduce ktime_to_ms() SUNRPC: RPC metrics and RTT estimator should use same RTT value NFS: Calldata for nfs4_renew_done() NFS: Squelch compiler warning in nfs_add_server_stats() ...
