Just a small funny I noticed.  In yaffs_guts.c we have:

static int yaffs_UnlinkWorker(yaffs_Object *obj)
{

        int immediateDeletion = 0;

        if (!obj->myInode)
                immediateDeletion = 1;

        if(obj)
                yaffs_UpdateParent(obj->parent);


Now the second if (obj) make no sense, we'd have already crashed and
burned on the obj->myInode dereference.

>From the immediate context I'm guessing it should be:

	if (obj->parent)
		yaffs_UpdateParent(obj->parent);
