Subject: [PATCH] udev: use bfq as the default scheduler
|
|
|
d7b2d46 |
|
|
|
d7b2d46 |
As requested in https://bugzilla.redhat.com/show_bug.cgi?id=1738828.
|
|
|
d7b2d46 |
Test results are that bfq seems to behave better and more consistently on
|
|
|
d7b2d46 |
typical hardware. The kernel does not have a configuration option to set
|
|
|
d7b2d46 |
the default scheduler, and it currently needs to be set by userspace.
|
|
