Subject: [PATCH v2 07/31] timer: Remove users of TIMER_DEFERRED_INITIALIZER
Date: Wed, 20 Sep 2017 16:27:31 -0700	[thread overview]
Message-ID: <1505950075-50223-8-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1505950075-50223-1-git-send-email-keescook@chromium.org>

This removes uses of TIMER_DEFERRED_INITIALIZER and chooses a location
to call setup_deferrable_timer() from before add_timer() or mod_timer()
is called.
