[PATCH] JFFS2: SUMMARY: fix a summary collecting bug
In some special case (padding because of sync or umount) it can be possible
that summary information is not fit to the end of the erase block. In
these cases the collecting of summary is disabled for this erase block.
The problem was that this was not respected by jffs2_sum_add_kvec(). This
patch fix this bug.
