From 3825827ebf9973600347b16e848f3de52262ab6b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 24 Jul 2018 14:27:11 -0400 Subject: [PATCH] NFS: More excessive attribute revalidation in nfs_execute_ok() execute_ok() will only check the mode bits if the object is not a directory, so we don't need to revalidate the attributes in that case.
