Subject: [PATCH RFC v5 6/8] pvqspinlock, x86: Rename paravirt_ticketlocks_enabled
Date: Wed, 26 Feb 2014 23:32:45 -0500 [thread overview]
Message-ID: <1393475567-4453-7-git-send-email-Waiman.Long@hp.com> (raw)
In-Reply-To: <1393475567-4453-1-git-send-email-Waiman.Long@hp.com>
This patch renames the paravirt_ticketlocks_enabled static key to a
more generic paravirt_spinlocks_enabled name.
