From 5f5837d2d650db25b9153b91535e67a96b265f58 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 16 Dec 2013 16:38:49 -0800 Subject: [PATCH] bcache: Do bkey_put() in btree_split() error path This error path shouldn't have been hit in practice.. and we've got reworked reserve code coming soon so that it shouldn't _ever_ be bit... but if we've got code for this error path it should be correct.
