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. Signed-off-by: Shin'ichiro Kawasaki <shinichiro.kawasaki@wdc.com> --- common/rc | 8 ++++++++ 1 file changed, 8 insertions(+)
