There are two cases when handle DISCARD merge. If max_discard_segments == 1, the bios/requests need to be contiguous to merge. If max_discard_segments > 1, it takes every bio as a range and different range needn't to be contiguous. But now, attempt_merge screws this up. It always consider contiguity for DISCARD for the case max_discard_segments > 1 and cannot merge contiguous DISCARD for the case max_discard_segments == 1, because rq_attempt_discard_merge always returns false in this case. This patch fixes both of the two cases above.

Since commit 2d29c9f8 ("block, bfq: improve asymmetric scenarios detection"), a scenario is defined asymmetric when one of the following conditions holds: - active bfq_queues have different weights - one or more group of entities (bfq_queue or other groups of entities) are active bfq grants fairness and low latency also in such asymmetric scenarios, by plugging the dispatching of I/O if the bfq_queue in service happens to be temporarily idle. This plugging may lower throughput, so it is important to do it only when strictly needed. By mistake, in commit '2d29c9f8' ("block, bfq: improve asymmetric scenarios detection") the num_active_groups counter was firstly incremented and subsequently decremented at any entity (group or bfq_queue) weight change. This is useless, because only transitions from active to inactive and vice versa matter for that counter. Unfortunately this is also incorrect in the following case: the entity at issue is a bfq_queue and it is under weight raising. In fact in this case there is a spurious increment of the num_active_groups counter. This spurious increment may cause scenarios to be wrongly detected as asymmetric, thus causing useless plugging and loss of throughput. This commit fixes this issue by simply removing the above useless and wrong increments and decrements.

Drivers exposing zoned block devices have to initialize and maintain correctness (i.e. revalidate) of the device zone bitmaps attached to the device request queue (seq_zones_bitmap and seq_zones_wlock). To simplify coding this, introduce a generic helper function blk_revalidate_disk_zones() suitable for most (and likely all) cases. This new function always update the seq_zones_bitmap and seq_zones_wlock bitmaps as well as the queue nr_zones field when called for a disk using a request based queue. For a disk using a BIO based queue, only the number of zones is updated since these queues do not have schedulers and so do not need the zone bitmaps. With this change, the zone bitmap initialization code in sd_zbc.c can be replaced with a call to this function in sd_zbc_read_zones(), which is called from the disk revalidate block operation method. A call to blk_revalidate_disk_zones() is also added to the null_blk driver for devices created with the zoned mode enabled. Finally, to ensure that zoned devices created with dm-linear or dm-flakey expose the correct number of zones through sysfs, a call to blk_revalidate_disk_zones() is added to dm_table_set_restrictions(). The zone bitmaps allocated and initialized with blk_revalidate_disk_zones() are freed automatically from __blk_release_queue() using the block internal function blk_queue_free_zone_bitmaps().

Dispatching a report zones command through the request queue is a major pain due to the command reply payload rewriting necessary. Given that blkdev_report_zones() is executing everything synchronously, implement report zones as a block device file operation instead, allowing major simplification of the code in many places. sd, null-blk, dm-linear and dm-flakey being the only block device drivers supporting exposing zoned block devices, these drivers are modified to provide the device side implementation of the report_zones() block device file operation. For device mappers, a new report_zones() target type operation is defined so that the upper block layer calls blkdev_report_zones() can be propagated down to the underlying devices of the dm targets. Implementation for this new operation is added to the dm-linear and dm-flakey targets.

Expose through sysfs the nr_zones field of struct request_queue. Exposing this value helps in debugging disk issues as well as facilitating scripts based use of the disk (e.g. blktests). For zoned block devices, the nr_zones field indicates the total number of zones of the device calculated using the known disk capacity and zone size. This number of zones is always 0 for regular block devices. Since nr_zones is defined conditionally with CONFIG_BLK_DEV_ZONED, introduce the blk_queue_nr_zones() function to return the correct value for any device, regardless if CONFIG_BLK_DEV_ZONED is set.

There is no need to synchronously execute all REQ_OP_ZONE_RESET BIOs necessary to reset a range of zones. Similarly to what is done for discard BIOs in blk-lib.c, all zone reset BIOs can be chained and executed asynchronously and a synchronous call done only for the last BIO of the chain. Modify blkdev_reset_zones() to operate similarly to blkdev_issue_discard() using the next_bio() helper for chaining BIOs. To avoid code duplication of that function in blk_zoned.c, rename next_bio() into blk_next_bio() and declare it as a block internal function in blk.h.

Handling checks of ZBC device capacity using the max_lba field of the REPORT ZONES command reply for disks with rc_basis == 0 can be done using the same report zones command reply used to check the "same" field. Avoid executing a report zones command solely to check the disk capacity by merging sd_zbc_check_capacity() into sd_zbc_check_zone_size() and renaming that function to sd_zbc_check_zones(). This removes a costly execution of a full report zones command and so reduces device scan duration at boot time as well as the duration of disk revalidate calls. Furthermore, setting the partial report bit in the REPORT ZONES command cdb can significantly reduce this command execution time as the device does not have to count and report the total number of zones that could be reported assuming a large enough reply buffer. A non-partial zone report is necessary only for the first execution of report zones used to check the same field value (to ensure that this value applies to all zones of the disk). All other calls to sd_zbc_report_zones() can use a partial report to reduce execution time. Using a 14 TB ZBC disk, these simple changes reduce device scan time at boot from about 3.5s down to about 900ms. Disk revalidate times are also reduced from about 450ms down to 230ms.
