Subject: [PATCH v2 01/11] block: widen BlockLimits.zone_size to uint64_t
Date: Wed, 2 Sep 2026 21:44:12 +0200 [thread overview]
Message-ID: <20260902194423.759355-2-cassel@kernel.org> (raw)
In-Reply-To: <20260902194423.759355-1-cassel@kernel.org>
From: Sam Li <faithilikerun@gmail.com>
The zone-size field in BlockLimits is currently uint32_t, capping
expressible zone sizes at 4 GiB. Real zoned-device protocols
like NVMe ZNS allow larger zones. Widen BlockLimits.zone_size to
uint64_t to match.
