From ae2bb03236fc978bdf673c19d39832500793b83c Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Tue, 2 Oct 2012 14:49:52 -0700 Subject: NFSv4: don't put ACCESS in OPEN compound if O_EXCL Don't put an ACCESS op in OPEN compound if O_EXCL, because ACCESS will return permission denied for all bits until close.
