From d6c67a4fee866ad95fe1d727f80a56f956737706 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 1 May 2015 11:08:59 -0700 Subject: [PATCH] f2fs: revmove spin_lock for write_orphan_inodes This patch removes spin_lock, since this is covered by f2fs_lock_op already. And, we should avoid to use page operations inside spin_lock.
