From: Andrew Patterson Date: Thu, 4 Sep 2008 20:27:30 +0000 (-0600) Subject: Check for device resize when rescanning partitions X-Git-Tag: v2.6.28-rc1~733^2~52 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=9bc3ffbfbdf71fefda8a261ef8d6fdc388a29b42;p=linux-2.6-omap-h63xx.git Check for device resize when rescanning partitions Check for device resize in the rescan_partitions() routine. If the device has been resized, the bdev size is set to match. The rescan_partitions() routine is called when opening the device and when calling the BLKRRPART ioctl.
