From a69aef1496726ed88386dad65abfcc8cd3195304 Mon Sep 17 00:00:00 2001 From: Fred Isaman Date: Thu, 3 Mar 2011 15:13:47 +0000 Subject: NFSv4.1: pnfs filelayout driver write Allows the pnfs filelayout driver to write to the data servers. Note that COMMIT to data servers will be implemented in a future patch. To avoid improper behavior, for the moment any WRITE to a data server that would also require a COMMIT to the data server is sent NFS_FILE_SYNC.
