Subject: [PATCH 02/10] block: Unhash also block device inode for the whole device
Date: Thu, 9 Feb 2017 13:44:25 +0100 [thread overview]
Message-ID: <20170209124433.2626-3-jack@suse.cz> (raw)
In-Reply-To: <20170209124433.2626-1-jack@suse.cz>
Iteration over partitions in del_gendisk() omits part0. Add
bdev_unhash_inode() call for the whole device. Otherwise if the device
number gets reused, bdev inode will be still associated with the old
(stale) bdi.
