@luoyuan3471 yes! ReadLock.lock() will call function(tryAcquireShared), this method will check whether the waiting queue first node is shared. if false, lock method will be blocked even if sharedCount(c) >0.But readLock.tryLock() do not need the check, it can get the csqueue readLock directly. you can diff tryReadLock() and Lock(), it's an interesting design. -- This is an automated message from the Apache Git Service.
