MDEV-5019 - THREADPOOL - Create Information Schema Table for Threadpool

 

Hi guys!
I openned a new MDEV https://mariadb.atlassian.net/browse/MDEV-5019 the
idea is expose the threadpool group information like oracle thread pool
(more information about oracle thread pool here:
http://mikaelronstrom.blogspot.com.br/2011_10_01_archive.html)

I can help, but i don't know how access the threadpool at
scheduler.h/scheduler.c from a information schema plugin

1) lock important mutex and others mdl
2) acess variables
3) write information schema based on variables

1 and 2 i don't know how to do :(
can anyone help ? :)

thanks guys :)
