Towards this end, I came up with the following patch to Documentation/kernel-parameters.txt. Not sure if it needs ACKs or anything, but I wanted to make sure dzickus saw it. This will resolve BZ 454792. This version doesn't tell the user to divide by zero (thanks Alan). -- Chris Lalancette diff --git a/Documentation/kernel-parameters.txt b/Documentation/kernel-parameters.txt index b5bbd11..20ab2a9 100644 --- a/Documentation/kernel-parameters.txt +++ b/Documentation/kernel-parameters.txt @@ -470,6 +470,10 @@ running once the system is up.
