This series adds sysfs files that expose the inline encryption capabilities of request queues. 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 applies to linux-block/for-next. Changed v1 => v2: - Use sysfs_emit() instead of sprintf(). - Use __ATTR_RO().
