Subject: [PATCH v2 0/2] block: Generalize physical entry definition
Date: Mon, 17 Nov 2025 21:22:42 +0200	[thread overview]
Message-ID: <20251117-nvme-phys-types-v2-0-c75a60a2c468@nvidia.com> (raw)

Changelog:
v2:
 * Added Chaitanya's Reviewed-by tags.
 * Removed explicit casting from size_t to unsigned int.
v1: https://patch.msgid.link/20251115-nvme-phys-types-v1-0-c0f2e5e9163d@kernel.org

--------------------------------------------------------------------------------
The block layer code is declared "struct phys_vec" entry which describes
contiguous chunk of physical memory. That definition is useful for all
possible users of DMA physical address-based API.

This series changes NVMe code to support larger chunks of memory by changing
length field from u32 to be size_t, which will be u64 on 64-bits platforms,
and promotes "struct phys_vec" to general place.
