So one of the possible solutions could be moving `pend_reprios` from `struct tcb_s` to a `struct semholder_s`, but that would grow memory consumption a lot. I tried to prototype changes where I save only the prio of highest priority task waiting on semaphore in `struct semholder_s`, but that fails in case if we are having multiple tasks with the same priority. So we definitely need to track both the origin of reprio and reprio priority. That is why I wrote that one of the possible solutions could be to "equip each semaphore with a list of tasks waiting for that semaphore and when task release a semaphore it iterates the tasks wait list for all semaphores that it holds and find the highest priority from that lists" so we will can rely on the actual data when task release the semaphore. -- This is an automated message from the Apache Git Service.
