From 843ccf9f46baff289946e897b11fd813de62d06f Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 24 Aug 2018 14:56:28 +0200 Subject: btrfs: use assertion helpers for spinning writers Use the helpers where open coded. On non-debug builds, the warnings will not trigger and extent_buffer::spining_writers become unused and can be moved to the appropriate section, saving a few bytes.
