Trond Myklebust 837bb1d752 NFSv4.2: Fix writeback races in nfs4_copy_file_range ... 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.
