Re: [PATCH 3/3] mm: mmap_lock: add ip to mmap_lock tracepoints

Hi Steven! Sorry to bother you ;)

(I resend this email because the last one was not cc to mailing list.)

It has been ten days since my last email. What's your opinion about my 
patch "[PATCH 3/3] mm: mmap_lock: add ip to mmap_lock tracepoints"? 
Briefly, lock events are so frequent that ip collection and lock event 
collection cannot be separated, otherwise it will cause the wrong order 
of data.

I am developing a tool to analyze mmap_lock contend using this feature. 
Adding ip to mmap_lock tracepoints is quite convenient.

Sorry to bother you again. Hoping for your reply. Thanks!
