Subject: [PATCH v3 1/7] block: convert nr_requests to unsigned int
Date: Fri, 10 Oct 2025 10:28:03 +0800 [thread overview]
Message-ID: <20251010022812.2985286-2-yukuai@kernel.org> (raw)
In-Reply-To: <20251010022812.2985286-1-yukuai@kernel.org>
From: Yu Kuai <yukuai3@huawei.com>
This value represents the number of requests for elevator tags, or drivers
tags if elevator is none. The max value for elevator tags is 2048, and
in drivers at most 16 bits is used for tag.
