Subject: [PATCH] test/udev-test.pl: test correctness of symlink targets
21255d
21255d
Test if symlinks are created correctly by comparing the symlink
21255d
targets to the devnode path. This implies (for the symlink) that
21255d
major/minor numbers and permissions are correct, as we have tested
21255d
that on the devnode already.
21255d
21255d
(cherry picked from commit 997683c8f152e1c139a7ce537de81a0aeae4627f)
