From 01cd33674e95296e1647da3534b9aef1e98556b5 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 3 Jun 2013 21:39:49 -0400 Subject: [PATCH] Btrfs: put our inode if orphan cleanup fails When we cross into a different subvol when doing a lookup we will run the orhpan cleanup. If this fails however we do not drop the ref to the inode we were looking up before we return an error, which leads to busy inodes on umount.
