Date: Mon, 26 Jan 2015 14:47:08 -0300	[thread overview]
Message-ID: <1422294449-12735-6-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1422294449-12735-1-git-send-email-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

The code being used when decaying and deleting entries from a hists
instance was the same, provide a function to avoid code dup.
