scsi: sd_zbc: Improve report zones error printout

2019-11-27T02:43:22Z

In the case of a report zones command failure, instead of simply printing the host_byte and driver_byte values returned, print a message that is more human readable and useful, adding sense codes too. To do so, use the already defined sd_print_sense_hdr() and sd_print_result() functions by moving the declaration of these functions into sd.h.

block: rework zone reporting

2019-11-13T02:12:07Z

Avoid the need to allocate a potentially large array of struct blk_zone in the block layer by switching the ->report_zones method interface to a callback model. Now the caller simply supplies a callback that is executed on each reported zone, and private data for it.

scsi: implement REQ_OP_ZONE_RESET_ALL

2019-08-05T03:41:29Z

This patch implements the zone reset all operation for sd_zbc.c. We add a new boolean parameter for the sd_zbc_setup_reset_cmd() to indicate REQ_OP_ZONE_RESET_ALL command setup. Along with that we add support in the completion path for the zone reset all. Reviewed-by: Hannes Reinecke Reviewed-by: Damien Le Moal Signed-off-by: Chaitanya Kulkarni Acked-by: Martin K.

block: Kill gfp_t argument of blkdev_report_zones()

2019-07-12T02:04:37Z

Only GFP_KERNEL and GFP_NOIO are used with blkdev_report_zones(). In preparation of using vmalloc() for large report buffer and zone array allocations used by this function, remove its "gfp_t gfp_mask" argument and rely on the caller context to use memalloc_noio_save/restore() where necessary (block layer zone revalidation and dm-zoned I/O error path).

scsi: sd: Fix typo in sd_first_printk()

2019-02-13T03:33:00Z

Commit b2bff6ceb61a9 ("[SCSI] sd: Quiesce mode sense error messages") added the macro sd_first_printk(). The macro takes "sdsk" as argument but dereferences "sdkp". This hasn't caused any real issues since all callers of sd_first_printk() have an sdkp. But fix the typo.

scsi: sd: Make protection lookup tables static and relocate functions

2019-01-09T03:29:32Z

Currently the protection lookup tables in sd_prot_flag_mask() and sd_prot_op() are declared as non-static. As such, they will be rebuilt for each respective function call. Optimise by making them static. This saves ~100B object code for sd.c: Before: text data bss dec hex filename 25403 1024 16 26443 674b drivers/scsi/sd.o After: text data bss dec hex filename 25299 1024 16 26339 66e3 drivers/scsi/sd.o In addition, since those same functions are declared in sd.h, but each are only referenced in sd.c, relocate them to that same c file. The inline specifier is dropped also, since gcc should be able to make the decision to inline. Signed-off-by: John Garry Reviewed-by: Bart Van Assche Signed-off-by: Martin K. Petersen

block: Introduce blk_revalidate_disk_zones()

2018-10-25T17:17:40Z

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().
