Upstream udev dev will not read the device information from /proc, and will also not call any external tools like grep. This all needs to be solved properly on the kernel side, to export real devices and allow efficient and reliable matching from userspace tools.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
