From 778d28172f710184855bcfeadcdd6b46997c4de2 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 27 Apr 2012 13:48:19 -0400 Subject: [PATCH] NFSv4: Simplify the NFSv4 REMOVE, LINK and RENAME compounds Get rid of the post-op GETATTR on the directory in order to reduce the amount of processing done on the server.
