Are the parts where interrupts are enabled pre-emptable? If a rt task is
executing one of these interruptible regions of code and an interrupt
comes in
that makes a higher priority rt task runnable, will the task switch occur

immediately or is it delayed until the first task has finished the
"system
call" (OK, it's not a system call in the Linux kernel sense, but you know
what
I mean).
