Subjectblock: move all core partition code from fs/partitions/check.c to block/
From
Date
From: Kay Sievers <kay.sievers@vrfy.org>
Subject: block: move all core partition code from fs/partitions/check.c to block/

Only the actual partition parsing code should be left in fs/partitions now,
and the driver core/sysfs code for partitions has moved to block/partition.c.
