Subject: [Qemu-devel] [PATCH v4 12/12] tcg: rename tb_find_physical()
Date: Fri, 15 Jul 2016 20:58:52 +0300	[thread overview]
Message-ID: <20160715175852.30749-13-sergey.fedorov@linaro.org> (raw)
In-Reply-To: <20160715175852.30749-1-sergey.fedorov@linaro.org>

From: Sergey Fedorov <serge.fdrv@gmail.com>

In fact, this function does not exactly perform a lookup by physical
address as it is descibed for comment on get_page_addr_code(). Thus
it may be a bit confusing to have "physical" in it's name. So rename it
to tb_htable_lookup() to better reflect its actual functionality.
