From cdce5d6b94b6182f6d8a5b7b52923933e98cbc92 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 18 Oct 2005 14:20:18 -0700 Subject: [PATCH] VFS: Make link_path_walk set LOOKUP_CONTINUE before calling permission(). This will allow nfs_permission() to perform additional optimizations when walking the path, by folding the ACCESS(MAY_EXEC) call on the directory into the lookup revalidation.
