From 15392efb9d427482754f6d267262452878667499 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 7 Jul 2010 16:51:28 +0200 Subject: [PATCH] block: remove BKL from partition ioctls The blkpg_ioctl and blkdev_reread_part access fields of the bdev and gendisk structures, yet they always do so under the protection of bdev->bd_mutex, which seems sufficient.
