Eric Dumazet cda210a4bd ptp: annotate data-race around q->head and q->tail ... [ Upstream commit 73bde5a329 ] 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.")
