Subject: [PATCH net-next 06/15] qed: move chain initialization inlines next to allocation functions
Date: Wed, 22 Jul 2020 18:53:40 +0300
Message-ID: <20200722155349.747-7-alobakin@marvell.com> (raw)
In-Reply-To: <20200722155349.747-1-alobakin@marvell.com>

qed_chain_init*() are used in one file/place on "cold" path only, so they
can be uninlined and moved next to the call sites.
