From 9a5e1ea1e1e539e244a54afffc330fc368376ab9 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Mon, 29 Sep 2008 11:24:41 -0400 Subject: Btrfs: drop WARN_ON from btrfs_add_leaf_ref btrfs_add_leaf_ref was doing checks on the objects it found in the rbtree to make sure they were properly linked into the tree. But, the field it was checking can be safely changed outside of the tree spin lock. The WARN_ON was for debugging the initial implementation and can be safely removed.
