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!
