From f72ad18e996338a8033aeb981e645f8dbf4e22c1 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Mon, 30 Jan 2017 12:24:37 -0800 Subject: Btrfs: pass delayed_refs directly to btrfs_find_delayed_ref_head All we need is @delayed_refs, all callers have get it ahead of calling btrfs_find_delayed_ref_head since lock needs to be acquired firstly, there is no reason to deference it again inside the function.
