Subject: [PATCH blktests 1/3] common/rc: Add _test_dev_max_active_zones() helper function
Date: Thu, 1 Oct 2020 19:15:29 +0900 [thread overview]
Message-ID: <20201001101531.333879-2-shinichiro.kawasaki@wdc.com> (raw)
In-Reply-To: <20201001101531.333879-1-shinichiro.kawasaki@wdc.com>
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. To refer the attribute from test cases,
introduce the helper function _test_dev_max_active_zones(). If the
attribute is available, the function returns the attribute value.
Otherwise, returns 0 to indicate that the device does not have the limit.
