Merge branch 'nfs-for-2.6.36' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6
* 'nfs-for-2.6.36' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (42 commits) NFS: NFSv4.1 is no longer a "developer only" feature NFS: NFS_V4 is no longer an EXPERIMENTAL feature NFS: Fix /proc/mount for legacy binary interface NFS: Fix the locking in nfs4_callback_getattr SUNRPC: Defer deleting the security context until gss_do_free_ctx() SUNRPC: prevent task_cleanup running on freed xprt SUNRPC: Reduce asynchronous RPC task stack usage SUNRPC: Move the bound cred to struct rpc_rqst SUNRPC: Clean up of rpc_bindcred() SUNRPC: Move remaining RPC client related task initialisation into clnt.c SUNRPC: Ensure that rpc_exit() always wakes up a sleeping task SUNRPC: Make the credential cache hashtable size configurable SUNRPC: Store the hashtable size in struct rpc_cred_cache NFS: Ensure the AUTH_UNIX credcache is allocated dynamically NFS: Fix the NFS users of rpc_restart_call() SUNRPC: The function rpc_restart_call() should return success/failure NFSv4: Get rid of the bogus RPC_ASSASSINATED(task) checks NFSv4: Clean up the process of renewing the NFSv4 lease NFSv4.1: Handle NFS4ERR_DELAY on SEQUENCE correctly NFS: nfs_rename() should not have to flush out writebacks ...
