We're not modifying the nfs_server when we call nfs_inc_server_stats and friends, so allow the compiler to pass 'const' pointers too. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

The fs/nfs/iostat.h header has definitions that were designed to be exposed to user space. Move these definitions under include/linux so user space can use the definitions in applications that read /proc/self/mountstats. Also address a handful of coding style issues called out by checkpatch.pl in fs/nfs/iostat.h.

The mount statistics patches introduced a call to nfs_free_iostats that is not only redundant, but actually causes an oops. Also fix a memory leak due to the lack of a call to nfs_free_iostats on unmount. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Make an inode or an nfs_server struct available in the logic that handles JUKEBOX/DELAY type errors so the NFS client can account for them. This patch is split out from the main nfs iostat patch to highlight minor architectural changes required to support this statistic. Test plan: None.

Add a per-superblock performance counter facility to the NFS client. This facility mimics the counters available for block devices and for networking. Expose these new counters via the new /proc/self/mountstats interface. Thanks to Andrew Morton and Trond Myklebust for their review and comments. Test plan: fsx and iozone on UP and SMP systems, with and without pre-emption. Watch for memory overwrite bugs, and performance loss (significantly more CPU required per op).
