From fa08139d5e02838ccabd9dcde22663d3b6780cad Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 21 Jul 2016 16:00:12 -0400 Subject: [PATCH] nfsd: drop unnecessary MAY_EXEC check from create We need an fh_verify to make sure we at least have a dentry, but actual permission checks happen later.
