Hi, When preemption is disabled, what happens if a timer interrupt occurs when a process is in a system call? I would guess the handler would update process times, and if a schedule is pending, it occurs as soon as the process returns from the system call. Is that correct? Another question - the irqs are disabled at times (like when a spinlock is held). Does this cause any lost timer ticks? Thanks, Bahadir -- Kernelnewbies: Help each other learn about the Linux kernel.
