From 5768dcdd7f7675f9540e648428c8a1cd7208a0fe Mon Sep 17 00:00:00 2001 From: Fan Li Date: Tue, 4 Aug 2015 13:27:51 +0800 Subject: [PATCH] f2fs: change the timing of f2fs_wait_on_page_writeback some backing devices need pages to be stable during writeback. It doesn't matter if the page is completely overwritten or already uptodate, it needs to wait before write.
