Subject: [PATCH 03/38] drbd: De-inline drbd_should_do_remote() and drbd_should_send_out_of_sync()
Date: Wed, 25 Nov 2015 11:53:36 +0100 [thread overview]
Message-ID: <1448448851-10343-4-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1448448851-10343-1-git-send-email-philipp.reisner@linbit.com>
From: Andreas Gruenbacher <agruen@linbit.com>
There is no need to have these two as inline functions. In addition,
drbd_should_send_out_of_sync() is only used in a single place, anyway.
