Should we add similar fast paths for spinlocks? After spinlock changes in May, they always call `WaitForSingleObject` which means they suffer from the same syscall overhead. I mentioned in the past that some source files (barrier.c, rwlock.c) use file-global spinlock when accessing _any_ object, so having fast paths could give noticeable performance improvement in some cases.
Yes; a spinlock is just a mutex. -- Best regards, LIU Hao
