block: add trace messages to zone write plugging
Add tracepoints to zone write plugging plug and unplug events. Examples for these events are: kworker/u10:4-393 [001] d..1. 282.991660: disk_zone_wplug_add_bio: 8,0 zone 16, BIO 8388608 + 128 kworker/0:1H-58 [ [000] d..1. 283.083294: blk_zone_wplug_bio: 8,0 zone 15, BIO 7864320 + 128 Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com> Signed-off-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Link: https://lore.kernel.org/r/20250715115324.53308-6-johannes.thumshirn@wdc.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
