Eric Dumazet 1f368fd612 ptp: annotate data-race around q->head and q->tail ... [ Upstream commit 73bde5a3294853947252cd9092a3517c7cb0cd2d ] As I was working on a syzbot report, I found that KCSAN would probably complain that reading q->head or q->tail without barriers could lead to invalid results. Add corresponding READ_ONCE() and WRITE_ONCE() to avoid load-store tearing. Fixes: d94ba80ebb ("ptp: Added a brand new class driver for ptp clocks.")
