Hi all.
I am in doubt about the linux kernel behaviour is this situation: supose a have the process A, with the highest realtime priority and SCHED_FIFO policy. The process then issues a syscall, say read():
1) Can I be sure that there will be no process switch during the syscall processing, even if the system call causes a page fault?
2) What if the process was a non-realtime processes (ordinary one, SCHED_OTHER)?
Thanks a lot. Fabiano
