From afd495a8264fb25cef49834b5c3559b8aaa612ee Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 24 Aug 2018 15:57:38 +0200 Subject: btrfs: use assertion helpers for spinning readers Use the helpers where open coded. On non-debug builds, the warnings will not trigger and extent_buffer::spining_readers become unused and can be moved to the appropriate section, saving a few bytes.
