Christoph Hellwig d86e716aa4 block: move zone related fields to struct gendisk
Move the zone related fields that are currently stored in
struct request_queue to struct gendisk as these are part of the highlevel
block layer API and are only used for non-passthrough I/O that requires
the gendisk.

Thomas Gleixner 38197ca176 block: Cleanup license notice
Remove the imprecise and sloppy:

  "This files is licensed under the GPL."

license notice in the top level comment.

1) The file already contains a SPDX license identifier which clearly
   states that the license of the file is GPL V2 only

2) The notice resolves to GPL v1 or later for scanners which is just
   contrary to the intent of SPDX identifiers to provide clear and non
   ambiguous license information. Aside of that the value add of this
   notice is below zero,

Bart Van Assche 6a5ac98465 block: Make struct request_queue smaller for CONFIG_BLK_DEV_ZONED=n
Exclude zoned block device members from struct request_queue for
CONFIG_BLK_DEV_ZONED == n. Avoid breaking the build by only building
the code that uses these struct request_queue members if
CONFIG_BLK_DEV_ZONED != n.
