From c5bfece2d6129131b4ade985e63bc35ddf5868d4 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 12 Apr 2013 16:45:34 +0200 Subject: nohz: Switch from "extended nohz" to "full nohz" based naming "Extended nohz" was used as a naming base for the full dynticks API and Kconfig symbols. It reflects the fact the system tries to stop the tick in more places than just idle. But that "extended" name is a bit opaque and vague. Rename it to "full" makes it clearer what the system tries to do under this config: try to shutdown the tick anytime it can. The various constraints that prevent that to happen shouldn't be considered as fundamental properties of this feature but rather technical issues that may be solved in the future.
