From 650a898342b3fa21c392c06a2b7010fa19823efa Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Fri, 29 Sep 2006 01:59:35 -0700 Subject: [PATCH] vfs: define new lookup flag for chdir In the "operation does permission checking" model used by fuse, chdir permission is not checked, since there's no chdir method. For this case set a lookup flag, which will be passed to ->permission(), so fuse can distinguish it from permission checks for other operations.
