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