From 30f8fe3e47c5bb5715aa80b2a2fa0cab8b218fae Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 23 Apr 2012 13:55:30 -0400 Subject: Btrfs: cache no acl on new inodes When running compilebench I noticed we were spending some time looking up acls on new inodes, which shouldn't be happening since there were no acls. This is because when we init acls on the inode after creating them we don't cache the fact there are no acls if there aren't any. Doing this adds a little bit of a bump to my compilebench runs.
