From 3d94ea51c1d8db6f41268a9d2aea5f5771e9a8d3 Mon Sep 17 00:00:00 2001 From: Joseph Qi Date: Wed, 11 Sep 2013 14:19:51 -0700 Subject: [PATCH] ocfs2: clean up dead code in ocfs2_acl_from_xattr() In ocfs2_acl_from_xattr(), if size is less than sizeof(struct posix_acl_entry), it returns ERR_PTR(-EINVAL) directly. Then assign (size / sizeof(struct posix_acl_entry)) to count which will be at least 1, that means the following branch (count < 0) and (count == 0) will never be true.
