2015-04-23NFS: Reduce time spent holding the i_mutex during fallocate()Anna Schumaker
At the very least, we should not be taking the i_mutex until after checking if the server even supports ALLOCATE or DEALLOCATE, allowing v4.0 or v4.1 to exit without potentially waiting on a lock.

2015-04-23NFS: Don't zap caches on fallocate()Anna Schumaker
This patch adds a GETATTR to the end of ALLOCATE and DEALLOCATE operations so we can set the updated inode size and change attribute directly. DEALLOCATE will still need to release pagecache pages, so nfs42_proc_deallocate() now calls truncate_pagecache_range() before contacting the server.

2014-09-30NFS: Implement SEEKAnna Schumaker
The SEEK operation is used when an application makes an lseek call with either the SEEK_HOLE or SEEK_DATA flags set. I fall back on nfs_file_llseek() if the server does not have SEEK support.
