From cddcd800189bc03745d576f913dc57692c6f439a Mon Sep 17 00:00:00 2001 From: Jeff Mahoney Date: Mon, 3 Oct 2011 23:23:23 -0400 Subject: btrfs: Fix kfree of member instead of structure Correctness fix: The kfree calls in the add_delayed_* functions free the node that's passed into it, but the node is a member of another structure. It works because it's always the first member of the containing structure, but it should really be using the containing structure itself.
