-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.
