Subject: [PATCH v3 1/8] bsg: increase number of devices
Date: Wed, 7 Jun 2023 20:22:42 +0200 [thread overview]
Message-ID: <20230607182249.22623-2-mwilck@suse.com> (raw)
In-Reply-To: <20230607182249.22623-1-mwilck@suse.com>
From: Hannes Reinecke <hare@suse.de>
Larger setups may need to allocate more than 32k bsg devices, so
increase the number of devices to the full range of minor device
numbers.
