From 1d5ccd1c422d7d292a9e45248aa36771900c6331 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 28 Aug 2009 12:12:24 -0700 Subject: ext[234]: move over to 'check_acl' permission model Don't implement per-filesystem 'extX_permission()' functions that have to be called for every path component operation, and instead just expose the actual ACL checking so that the VFS layer can now do it for us.
