Revision d90c732122a1f6d0efe388a8a204f67f144b2eb3 authored by Josef Bacik on 17 May 2011, 13:50:54 UTC, committed by Josef Bacik on 23 May 2011, 17:03:17 UTC
On lookup we only want to read the inode item, so leave the path spinning. Also we're just wholesale reading the leaf off, so map the leaf so we don't do a bunch of kmap/kunmaps. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
