Subject: [PATCH] tests/udev-test.pl: add multiple device test
|
|
|
bd1529 |
|
|
|
bd1529 |
Add 4 new tests using multiple devices. Number 2-4 use many
|
|
|
bd1529 |
devices claiming the same symlink, where only one device has
|
|
|
bd1529 |
a higher priority thatn the others. They fail sporadically with
|
|
|
bd1529 |
the current code, if a race condition causes the symlink to point
|
|
|
bd1529 |
to the wrong device. Test 4 is like test 2 with sleeps in between,
|
|
|
bd1529 |
it's much less likely to fail.
|
