Hi, I am trying to understand the I/O scheduling under linux.
I believe linux right now implements the elevator algorithm in only one direction...(CSCAN). Would it be possible to implement elevator in both directions ??
Also, I was trying to modify the scheduling algorithm slightly by redirecting the requests to a function that I wrote to sequence the requests based on some priority. To periodically move the requests from my Q to the linux Q I need to have a timer-based thread that does it (basically issues make_requests periodically for each request in the Q I maintain). However, I am not sure about how I can initialize this thread before any I/O can be handled...
please help.....anyone. thanks a lot in advance.
