2022-07-06block: move zone related fields to struct gendiskChristoph Hellwig
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.

2019-01-17block: Cleanup license noticeThomas Gleixner
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, Cc: Damien Le Moal <damien.lemoal@wdc.com> Cc: Matias Bjorling <mb@lightnvm.io> Cc: Christoph Hellwig <hch@lst.de> Cc: Jens Axboe <axboe@kernel.dk> Cc: linux-block@vger.kernel.org Fixes: 6a5ac9846508 ("block: Make struct request_queue smaller for CONFIG_BLK_DEV_ZONED=n") Reviewed-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2018-07-09block: Make struct request_queue smaller for CONFIG_BLK_DEV_ZONED=nBart Van Assche
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.
