236 KCSAN relies on observing that two accesses happen concurrently. Crucially, we
243 address set up, and then observe the watchpoint to fire, two accesses to the
253 compiler instrumenting plain accesses. For each instrumented plain access:
264 To detect data races between plain and marked accesses, KCSAN also annotates
265 marked accesses, but only to check if a watchpoint exists; i.e. KCSAN never
266 sets up a watchpoint on marked accesses. By never setting up watchpoints for
267 marked operations, if all accesses to a variable that is accessed concurrently
269 report the accesses.
