fairq disk scheduling now default

DSCHED_FQ was added to GENERIC, making it the default disk scheduling policy for master. You might want to refresh your memory of dsched and the fairq policy with some prior details and benchmarks.

Update: As Venkatesh Srinivas pointed out in the comments, adding DSCHED_FQ to GENERIC does not make it the default, but you no longer have to load the fairq module. Which raises the question, should fairq be the default?

  1. Hi!

    The commit didn’t set FQ as the default scheduler; no-op should still be the default. Its just that the fairq policy is available in GENERIC now.
