We need to ensure that any writes to the destination file are serialised with the copy, meaning that the writeback has to occur under the inode lock. Also relax the writeback requirement on the source, and rely on the stateid checking to tell us if the source rebooted. Add the helper nfs_filemap_write_and_wait_range() to call pnfs_sync_inode() as is appropriate for pNFS servers that may need a layoutcommit.

LAYOUTRETURN is "special" in that servers and clients are expected to work with old stateids. When the client sends a LAYOUTRETURN with an old stateid in it then the server is expected to only tear down layout segments that were present when that seqid was current. Ensure that the client handles its accounting accordingly. Signed-off-by: NJeff Layton <jeff.layton@primarydata.com> Signed-off-by: NAnna Schumaker <Anna.Schumaker@Netapp.com>

The newly added NFS v4.2 operations (ALLOCATE, DEALLOCATE, SEEK and CLONE) use a helper called nfs42_set_rw_stateid to select a stateid that is sent to the server. But they don't set the inode and state fields in the nfs4_exception structure, and this don't partake in the stateid recovery protocol. Because of this they will simply return errors insted of trying to recover a stateid when the server return a BAD_STATEID error. Additionally CLONE has the problem that it operates on two files and thus two stateids, and thus needs to call the exception handler twice to recover stateids. While we're at it stop grabbing an addititional reference to the open context in all these operations - having the file open guarantees that the open context won't go away. All this can be produces with the generic/168 and generic/170 tests in xfstests which stress the CLONE stateid handling.

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.
