Subject: [PATCH] udevd: event - fix event queue in daemenozied mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We would enforce that events could only be added to the queue from the
main process, but that brake in daemonized mode. Relax the restriction
to only allow one process to add events to the queue.
Reported by Mantas Mikulėnas.
