I think you are about to open a can of worms. So far, we had only one
global lock for the complete JFFS2 instance. If you really want to start
using the JFFS2 internal locking, then this should done thoroughly and
not case by case from one issue to the next. All this delayed write
stuff is currently not covered by tests.
