    debug: add notifier chain debugging · 1b2439db
    Arjan van de Ven authored
    during some development we suspected a case where we left something
    in a notifier chain that was from a module that was unloaded already...
    and that sort of thing is rather hard to track down.
    This patch adds a very simple sanity check (which isn't all that
    expensive) to make sure the notifier we're about to call is
    actually from either the kernel itself of from a still-loaded
    module, avoiding a hard-to-chase-down crash.
