From 90947ef26fa689a3252aa8282a01f60648e70fdb Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 13 Feb 2006 11:12:36 -0500 Subject: [PATCH] [PATCH] reiserfs: fix potential (unlikely) oops in reiserfs_get_acl This fixes a potential oops if there is an error reported by posix_acl_from_disk(). This is mostly theoretical due to the use of magics and checksums in xattrs, but is still possible.
