Subject: [PATCH v1 06/10] types: move phys_vec definition to common header
From: Leon Romanovsky <leonro@...dia.com>
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 by upcoming VFIO patches for dma-buf operations.
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.
