[linux-audio-dev] Realtime audio and IO schedulers

Hi, i wonder if there's a way to grant a process priority over all other processes when it comes to disk i/o.. Somewhat similar like SCHED_FIFO scheduling for cpu priorities. This would be very useful especially for high reliability hard disk recording. I mean it would be simply great to record 24 tracks in ardour and not having to worry about disk underrun [or overrun] when a cronjob kicks in that scans the whole filesystem.. I heard and read a bit about the new io schedulers in the 2.6.x kernels, but i wasn't able to find any infos specifically on this subject.. So anyone knows more? Please let us know! Maybe current io-schedulers actually take the cpu priorities [nice level or relatime priorities] into account when assigning io bandwidth to processes, but if so i wouldn't know where to look to find out..
