From 5ffef88ffeb730e1bf2da56a39a55e03d57a66c9 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Date: Wed, 4 Aug 2010 10:14:47 +0300 Subject: UBIFS: switch to RO mode after synchronizing In 'ubifs_garbage_collect()' on error path, we first switch to R/O mode, and then synchronize write-buffers (to make sure no data are lost). But the GC write-buffer synchronization will fail, because we are already in R/O mode. This patch re-orders this and makes sure we first synchronize the write-buffer, and then switch to R/O mode.
