Re: [meta-virtualization] [PATCH] irqbalance: fix build with musl

[Bruce Ashfield <bruce.ashfield@gmail.com>]

Rather than do this backport, I completed the long overdue update
to irqbalance that should already contain this patch.

There were quite a few adjustments needed, so I haven't pushed
this to master yet.

You can see the RFC version of the update on master-next.
