From eb01680d40802baad9a90ebaa9e3a267470ba6be Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 8 Dec 2010 12:24:01 -0500 Subject: [PATCH] Btrfs: do not BUG if we fail to remove the orphan item for dead snapshots Not being able to delete an orphan item isn't a horrible thing. The worst that happens is the next time around we try and do the orphan cleanup and we can't find the referenced object and just delete the item and move on.
