From 2a2a83de548f7afe2c27e51cbc9ff761cba2b61b Mon Sep 17 00:00:00 2001 From: Filipe Manana Date: Wed, 2 Nov 2016 10:55:18 +0000 Subject: [PATCH] Btrfs: remove rb_node field from the delayed ref node structure After the last big change in the delayed references code that was needed for the last qgroups rework, the red black tree node field of struct btrfs_delayed_ref_node is no longer used, so just remove it, this helps us save some memory (since struct rb_node is 24 bytes on x86_64) for these structures.
