2018-10-25block: Introduce blk_revalidate_disk_zones()Damien Le Moal3-198/+26
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().

2018-10-25block: add a report_zones methodChristoph Hellwig3-124/+53
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.

2018-10-25scsi: sd_zbc: Fix sd_zbc_check_zones() error checksDamien Le Moal1-11/+8
The unsigned 32 bits overflow check for the zone size value is already done within sd_zbc_check_zones() with the test: } else if (logical_to_sectors(sdkp->device, zone_blocks) > UINT_MAX) { so there is no need to check again for an out of range value in sd_zbc_read_zones(). Simplify the code and fix sd_zbc_check_zones() error return to -EFBIG instead of -ENODEV if the zone size is too large. Change the return type of sd_zbc_check_zones() to an int for the error code and return the zone size (zone_blocks) through a u32 pointer to avoid overflowing the signed 32 return value.

2018-10-25scsi: sd_zbc: Reduce boot device scan and revalidate timeDamien Le Moal1-54/+40
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.
