Modular, switchable I/O schedulersModular, switchable I/O schedulersPosted Sep 30, 2004 7:30 UTC (Thu) by axboe (subscriber, #904)In reply to: Modular, switchable I/O schedulers by manpreet Parent article: Modular, switchable I/O schedulers
That's not easily doable, since each queue can only have one io scheduler assigned and active. Additionally, the io scheduler requires exclusive access to the given queue. What you propose would require the old one be active from io completions and the new one working for submission and queueing.
