From 1c7c474c31aea6d5cb2fb35f31d9e9e91ae466b1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 3 Nov 2009 16:44:44 +0100 Subject: make generic_acl slightly more generic Now that we cache the ACL pointers in the generic inode all the generic_acl cruft can go away and generic_acl.c can directly implement xattr handlers dealing with the full Posix ACL semantics for in-memory filesystems.
