* There are very likely to be lock-related bugs stemming from when the
kevent_copyin() and kevent_copyout() functions stopped holding the
kqueue lock. It would be nice to have a lock testing mechanism to
check that the correct locks are held.. something like:
#define MTX_LOCKED 1
#define MTX_UNLOCKED 0
#if NDEBUG
#define LOCK_MONITOR(x) int x
#define lock_assert(x,y) assert((x) == (y))
#define lock_acquire(x,y) do { pthread_mutex_lock((x)); y = MTX_LOCKED } while (0)
#define lock_release(x,y) do { pthread_mutex_unlock((x)); y = MTX_UNLOCKED } while (0)
#else
#define LOCK_MONITOR(x) /**/
#define lock_assert(x,y) do {} while (0)
#define lock_acquire(x,y) do { pthread_mutex_lock((x)); } while (0)
#define lock_release(x,y) do { pthread_mutex_unlock((x)); } while (0)
#endif
struct foo {
LOCK_MONITOR(foo_lockstat);
}
...
lock_assert(&kn->kn_lockmon, MTX_LOCKED);
lock_assert(&kn->kn_lockmon, MTX_UNLOCKED);
* Add a counter that increments on each each kevent() call. When printing
debug information within kevent(), display the value of the counter.
This will be helpful when debugging a multithreaded program that may have
multiple kevent() calls executing in parallel.
