hi,
I was going through the code in _thread_change_priority(){..}
(threadchangepriority.c) and had doubt. below is the code snippet.
_Atomic_Fence( ATOMIC_ORDER_ACQ_REL );
/*
* Do not bother recomputing all the priority related information if
* we are not REALLY changing priority.
*/
if ( ( *filter )( the_thread, &new_priority, arg ) ) {
uint32_t my_generation;
my_generation = the_thread->priority_generation + 1;
the_thread->current_priority = new_priority;
* the_thread->priority_generation = my_generation;*
( *the_thread->Wait.operations->priority_change )(
the_thread,
new_priority,
the_thread->Wait.queue
);
how is the data race problem avoided while setting
the_thread->priority_generation?
Thanks,
Saurabh Gadia
