From 6d848a488ad83cc3891bb274691118f45ce6aab9 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 28 Aug 2009 12:04:28 -0700 Subject: [PATCH] shmfs: use 'check_acl' instead of 'permission' shmfs wants purely standard POSIX ACL semantics, so we can use the new generic VFS layer POSIX ACL checking rather than cooking our own 'permission()' function.
