Subject: [PATCH] tests/udev-test.pl: add multiple device test
21255d
21255d
Add 4 new tests using multiple devices. Number 2-4 use many
21255d
devices claiming the same symlink, where only one device has
21255d
a higher priority thatn the others. They fail sporadically with
21255d
the current code, if a race condition causes the symlink to point
21255d
to the wrong device. Test 4 is like test 2 with sleeps in between,
21255d
it's much less likely to fail.
21255d
