Linux kernel 5.9 introduced a new sysfs attribute "max_active_zones". It
is an attribute of zoned block devices which indicates the limit of zones
in open or close status. When zoned block devices has this limit, test cases
block/004 and zbd/003 fail since write operations in them open zones and the
number of open zones excceds the limit.

This patch series addresses the failures. The first patch introduces a
helper function to get the max_active_zones value. Following patches modify
the two test cases to avoid the failures.

Shin'ichiro Kawasaki (3):
  common/rc: Add _test_dev_max_active_zones() helper function
  block/004: Provide max_active_zones to fio command
  zbd/003: Reset zones when the test device has max_active_zones limit
