From fcf463b92a08686d1aeb1e66674a72eb7a8bfb9b Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Wed, 17 Dec 2025 11:41:24 +0200 Subject: [PATCH] types: move phys_vec definition to common header Move the struct phys_vec definition from block/blk-mq-dma.c to include/linux/types.h to make it available for use across the kernel. The phys_vec structure represents a physical address range with a length, which is used by the new physical address-based DMA mapping API. This structure is already used by the block layer and will be needed for DMA phys API users. Moving this definition to types.h provides a centralized location for this common data structure and eliminates code duplication across subsystems that need to work with physical address ranges.
