Subject: [PATCH] test/udev-test.pl: generator for large list of block devices
21255d
21255d
Manually listing all devices in the test definition becomes cumbersome with
21255d
lots of devices. Add a function that scans on all block devices in
21255d
the test sysfs and generates a list of devices to test.
21255d
