Hi kevin ,

PI stands for  Priority Inheritance.

Hi,
Looking into task_struct (include/linux/scehd.h) , we have:

        /* PI waiters blocked on a rt_mutex held by this task */
        struct plist_head pi_waiters;

Any ideas what "pi" stand for ?
I assume it has nothing to do with "pi" from mathematics...


rgs.
