From 544fed47af4d2174ac0b550e9c8da15c2dfdb117 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 27 Dec 2019 15:02:28 +0200 Subject: ptp: introduce ptp_cancel_worker_sync In order to effectively use the PTP kernel thread for tasks such as timestamping packets, allow the user control over stopping it, which is needed e.g. when the timestamping queues must be drained.
