This is handled by the jffs2_wbuf_recover function. This function does not fix up the erase block summary information that is collected for writing at the end of the block, which results in an incorrect summary (or BUG if the summary was found to be empty). As the summary is not essential (it is an optimisation), it may be disabled for the current erase block when this situation arises. This patch does that.
