From 1caf9342fc71d020e788a59598a44d4ea0136b36 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 19 Nov 2007 10:18:17 -0500 Subject: Btrfs: Make ACLs return EOPNOTSUPP for now There was a slight problem with ACL's returning EINVAL when you tried to set an ACL. This isn't correct, we should be returning EOPNOTSUPP, so I did a very ugly thing and just commented everybody out and made them return EOPNOTSUPP. This is only temporary, I'm going back to implement ACL's, but Chris wants to push out a release so this will suffice for now. Also Yan suggested setting reada to -1 in the delete case to enable backwards readahead, and in the listxattr case I moved path->reada = 2; to after the if (!path) check so we can avoid a possible null dereference.
