Date: Tue, 12 Oct 2010 12:24:45 -0700 From: Blaise Gassend <blaise@...lowgarage.com> To: linux-kernel@...r.kernel.org Subject: Kconfig.preempt advertises no longer existing hardirq-preempt option and related proc entries. Seems like the documentation for PREEMPT_HARDIRQS has fallen behind the code. I would like to submit the following patch to fix that situation. Anybody happen to know why the option and proc entry were removed? I would have loved to have used them...
