| |
Anyone thought about allowing soft RT (SCHED_FIFO or SCHED_RR) tasks with negative priorities? These would only be executed if no other tasks of any type are there. Giving a normal Linux task a niceness value won't do this, as the task will still get some CPU time.
I was just thinking back to past projects, and about a year ago I wished I had something like this to do background housekeeping tasks for a distributed application I was writing -- I wanted to do them if possible on a free system, and only schedule time on some system if they didn't get scheduled anyway.
Since I'm sure this isn't a new idea, any good reasons not to allow this? (surely there can't be security implications, right?) I'm not really interested in doing it myself right now, but I might in the future if there aren't good reasons otherwise.
