From 514ac8ad8793a097c0c9d89202c642479d6dfa34 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Fri, 3 Jan 2014 21:07:00 -0800 Subject: Btrfs: don't use ram_bytes for uncompressed inline items If we truncate an uncompressed inline item, ram_bytes isn't updated to reflect the new size. The fixe uses the size directly from the item header when reading uncompressed inlines, and also fixes truncate to update the size as it goes.
