No known partitioning tool supports zoned block devices, especially the host managed flavor with strong sequential write constraints. Furthermore, there are also no known user nor use cases for partitioned zoned block devices. This patch removes partition device creation for zoned block devices, which allows simplifying the processing of zone commands for zoned block devices. A warning is added if a partition table is found on the device. For report zones operations no zone sector information remapping is necessary anymore, simplifying the code. Of note is that remapping of zone reports for DM targets is still necessary as done by dm_remap_zone_report(). Similarly, remaping of a zone reset bio is not necessary anymore. Testing for the applicability of the zone reset all request also becomes simpler and only needs to check that the number of sectors of the requested zone range is equal to the disk capacity.

All kernel users of blkdev_report_zones() as well as applications use through ioctl(BLKZONEREPORT) expect to potentially get less zone descriptors than requested. As such, the use of the internal report zones command execution loop implemented by blk_report_zones() is not necessary and can even be harmful to performance by causing the execution of inefficient small zones report command to service the reminder of a requested zone array. This patch removes blk_report_zones(), simplifying the code. Also remove a now incorrect comment in dm_blk_report_zones(). Signed-off-by:

Damien Le Moal authored
For ZBC and ZAC zoned devices, the scsi driver revalidation processing implemented by sd_revalidate_disk() includes a call to sd_zbc_read_zones() which executes a full disk zone report used to check that all zones of the disk are the same size. This processing is followed by a call to blk_revalidate_disk_zones(), used to initialize the device request queue zone bitmaps (zone type and zone write lock bitmaps). To do so, blk_revalidate_disk_zones() also executes a full device zone report to obtain zone types. As a result, the entire zoned block device revalidation process includes two full device zone report. By moving the zone size checks into blk_revalidate_disk_zones(), this process can be optimized to a single full device zone report, leading to shorter device scan and revalidation times. This patch implements this optimization, reducing the original full device zone report implemented in sd_zbc_check_zones() to a single, small, report zones command execution to obtain the size of the first zone of the device. Checks whether all zones of the device are the same size as the first zone size are moved to the generic blk_check_zone() function called from blk_revalidate_disk_zones(). This optimization also has the following benefits: 1) fewer memory allocations in the scsi layer during disk revalidation as the potentailly large buffer for zone report execution is not needed. 2) Implement zone checks in a generic manner, reducing the burden on device driver which only need to obtain the zone size and check that this size is a power of 2 number of LBAs. Any new type of zoned block device will benefit from this. Signed-off-by:

blk-cgroup has been using blkg_rwstat to track basic IO stats. Unfortunately, reading recursive stats scales badly as itinvolves walking all descendants. On systems with a huge number of cgroups (dead or alive), this can lead to substantial CPU cost when reading IO stats. This patch reimplements basic IO stats using cgroup rstat which uses more memory but makes recursive stat reading O(# descendants which have been active since last reading) instead of O(# descendants). * blk-cgroup core no longer uses sync/async stats. Introduce new stat enums - BLKG_IOSTAT_{READ|WRITE|DISCARD}. * Add blkg_iostat[_set] which encapsulates byte and io stats, last values for propagation delta calculation and u64_stats_sync for correctness on 32bit archs. * Update the new percpu stat counters directly and implement blkcg_rstat_flush() to implement propagation. * blkg_print_stat() can now bring the stats up to date by calling cgroup_rstat_flush() and print them instead of directly summing up all descendants. * It now allocates 96 bytes per cpu. It used to be 40 bytes. Signed-off-by: -

Zoned block devices (ZBC and ZAC devices) allow an explicit control over the condition (state) of zones. The operations allowed are: * Open a zone: Transition to open condition to indicate that a zone will actively be written * Close a zone: Transition to closed condition to release the drive resources used for writing to a zone * Finish a zone: Transition an open or closed zone to the full condition to prevent write operations To enable this control for in-kernel zoned block device users, define the new request operations REQ_OP_ZONE_OPEN, REQ_OP_ZONE_CLOSE and REQ_OP_ZONE_FINISH as well as the generic function blkdev_zone_mgmt() for submitting these operations on a range of zones. This results in blkdev_reset_zones() removal and replacement with this new zone magement function. Users of blkdev_reset_zones() (f2fs and dm-zoned) are updated accordingly.

REQ_OP_ZONE_RESET operations cannot be merged as these bios and requests do not have a size and are never sequential due to the zone start sector position required for their execution.

blkcg_print_stat() iterates blkgs under RCU and doesn't test whether the blkg is online. This can call into pd_stat_fn() on a pd which is still being initialized leading to an oops. The heaviest operation - recursively summing up rwstat counters - is already done while holding the queue_lock. Expand queue_lock to cover the other operations and skip the blkg if it isn't online yet. The online state is protected by both blkcg and queue locks, so this guarantees that only online blkgs are processed. Signed-off-by:

In scsi_mq_setup_tags(), cmd_size is calculated based on zero size for the scatter-gather list in case the low level driver uses SG_NONE in its host template. cmd_size is passed on to the block layer for calculation of the request size, and we've seen NULL pointer dereference errors from the block layer in drivers where SG_NONE is used and a mq IO scheduler is active, apparently as a consequence of this (see commit 68ab2d76 ("scsi: cxlflash: Set sg_tablesize to 1 instead of SG_NONE"), and a recent patch by Finn Thain converting the three m68k NFR5380 drivers to avoid setting SG_NONE). Try to avoid these errors by accounting for at least one sg list entry when calculating cmd_size, regardless of whether the low level driver set a zero sg_tablesize. Tested on 030 m68k with the atari_scsi driver - setting sg_tablesize to SG_NONE no longer results in a crash when loading this driver.
