From ed1b4ed79df258f08f16eac4a4fb96dc6d1a0f3a Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 24 Aug 2018 16:31:17 +0200 Subject: btrfs: switch extent_buffer::lock_nested to bool The member is tracking simple status of the lock, we can use bool for that and make some room for further space reduction in the structure.
