NFSv4.2: LAYOUTSTATS is optional to implement

2015-06-27T15:48:58+00:00

NFS: Reduce time spent holding the i_mutex during fallocate()

2015-04-23T18:36:28+00:00

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. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

NFS: Don't zap caches on fallocate()

2015-04-23T18:36:28+00:00

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.
