From 6311b10800a4bdc3f2c85d01fb113cf49bb83770 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 23 Jul 2011 17:36:50 +0200 Subject: xfs: cache negative ACLs if there is no attribute fork Always set up a negative ACL cache entry if the inode doesn't have an attribute fork. That behaves much better than doing this check inside ->check_acl.
