From aaf9607516ed38825268515ef4d773289a44f429 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 6 Feb 2015 18:53:45 -0800 Subject: [PATCH] f2fs: check node page contents all the time In get_node_page, if the page is up-to-date, we assumed that the page was not reclaimed at all. But, sometimes it was reported that its contents was missing. So, just for sure, let's check its mapping and contents.
