Skip instructions before setting up watchpoint
In linux kernel since version 5.1
(release Date: 2019-05-05)
watchpoint is set up, i.e. one in KCSAN_WATCH_SKIP per-CPU
memory operations are used to set up a watchpoint. A smaller value
results in more aggressive race detection, whereas a larger value
improves system performance at the cost of missing some races.
