The two issues are not related.  This is a confirmed bug in the kernel
where it always sets the size of the extended partition to 2 sectors,
even when the second sector is not there since it is the first sector of
the logical partition.  The BLKPG patch just causes the error to show
up immediately instead of after a reboot, since without the patch
BLKRRPART fails and the partition table is not read until reboot.
