From 7006f6eca874cd44d37ccb8cfeb8bed04e3bff22 Mon Sep 17 00:00:00 2001 From: Alasdair G Kergon Date: Tue, 3 Oct 2006 01:15:21 -0700 Subject: [PATCH] dm: export blkdev_driver_ioctl Export blkdev_driver_ioctl for device-mapper. If we get as far as the device-mapper ioctl handler, we know the ioctl is not a standard block layer BLK* one, so we don't need to check for them a second time and can call blkdev_driver_ioctl() directly.
