Several parameters for zoned devices are missing from lsblk's columns. This
series introduces them as following.
Column Name Description Sysfs path
------------------------------------------------------------------
ZONE-SZ zone size queue/chunk_sectors
ZONE-GRAN zone write granularity queue/zone_write_granularity
ZONE-APP zone append max bytes queue/zone_append_max_bytes
ZONE-NR number of zones queue/nr_zones
ZONE-OMAX max open zones queue/max_open_zones
ZONE-AMAX max active zones queue/max_active_zones
These columns are also added to the "-z" output.
Sample output:
$ lsblk -z -i

Naohiro Aota (3):
lsblk: factor out function to read sysfs param as bytes
lsblk: add columns of zoned parameters
lsblk: add zoned columns to "lsblk -z"
