From d810a4be1a625aafb2602c56c1256047f1e27380 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Thu, 7 Dec 2017 18:52:54 +0100 Subject: [PATCH] btrfs: add separate helper for unlock_extent_cached with GFP_ATOMIC There's only one instance where we pass different gfp mask to unlock_extent_cached. Add a separate helper for that and then we can drop the gfp parameter from unlock_extent_cached.
