From 8188df1733d6722336e287cc859b2567ad70576a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 23 Apr 2013 14:31:19 -0400 Subject: NFSv4.1: Use the more efficient open_noattr call for open-by-filehandle When we're doing open-by-filehandle in NFSv4.1, we shouldn't need to do the cache consistency revalidation on the directory. It is therefore more efficient to just use open_noattr, which returns the file attributes, but not the directory attributes.
