Priority inheritance in Linux & an offtopic question



1. Does Linux has a built-in priority inheritance mechanisms for
mutexes (in order to avoid priority inversion) ?
I tried to find it on LinuxThreads Frequently Asked
Questions and it's links--not with much success (but then it wasn't
an in-depth search). 
                              
By built-in I mean a special parameter for the mutex creating
function, so that when the mutex will be used by a low
priority process/thread,  it will elevate
the priority of the process to the priority of the  higher
priority process also using this mutex
(i.e. like THREAD_PRIO_PROTECT on pthread_mutexattr_getprotocol(...)  on
Solaris) .

2 Sory for asking this here- but maybe someone know about this on
Digital Unix?
