From e144cbcc251f16c1a14b9256cda73ab4aebe933a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 28 Apr 2012 16:05:03 -0400 Subject: NFSv4: Retrieve attributes _before_ calling delegreturn In order to retrieve cache consistency attributes before anyone else has a chance to change the inode, we need to put the GETATTR op _before_ the DELEGRETURN op. We can then use that as part of a 'nfs_post_op_update_inode_force_wcc()' call, to ensure that we update the attributes without clearing our cached data.
