ADDR TYPE HELD MINSPL OLDSPL WAITERS 0000030001054000 adapt 200000000 - - yes

is there some other cmds to get the thread which own it or which wait it?

Yes, you could found the mutex onwer from ::mutex output.

And you also can get all of threads related to one lock address by using:

<lock addr>::whatthread or <lock addr>::kgrep |::whatis -a

Then, try to use ::findstack to wok with a thread address...

Since you are from China, one of my Chinese blogs could give you an example about ::rwlock, but it's quite similar with ::mutex
