From 7cb1a5351da8ac499d965a78e94c79ad27891f43 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" <djwong@us.ibm.com> Date: Wed, 18 May 2011 13:53:20 -0400 Subject: [PATCH] ext4: clean up some wait_on_page_writeback calls wait_on_page_writeback already checks the writeback bit, so callers of it needn't do that test.
