Patches 1 and 2 are some related cleanups for existing blk-sysfs code. Patch 3 is the real change; see there for more details. This is based on top of my other patch series "[PATCH v2 0/8] docs: consolidate sysfs-block into Documentation/ABI/" (https://lore.kernel.org/r/20211208005640.102814-1-ebiggers@kernel.org). Changed v2 => v3: - Moved the documentation into Documentation/ABI/stable/sysfs-block, and improved it a bit. - Write "/sys/block/" instead of "/sys/class/block/". - Added Reviewed-by tags. Changed v1 => v2: - Use sysfs_emit() instead of sprintf(). - Use __ATTR_RO().
