From c8a429a465f9aaabe7fc7ddf5f34ff6dd188a68f Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 29 Jul 2009 15:40:57 -0700 Subject: [PATCH] Staging: hv: remove timer wrapper functions Use a real timer (there's only one in the code), no wrapper is needed, it just increases the complexity for no reason.
