From 9d510db423303b4f3555074dd7bdd0d692e432a4 Mon Sep 17 00:00:00 2001 From: "Matthew L. Creech" Date: Fri, 6 May 2011 18:58:23 -0400 Subject: UBIFS: fix-up free space on mount if flag is set If a UBIFS filesystem is being mounted read-write, or is being remounted from read-only to read-write, check for the "space_fixup" flag and fix all LEBs containing empty space if necessary.
