Subject: [PATCH 2/3] xen/ballon: Avoid calling dummy function __online_page_set_limits()
Date: Sun,  8 Sep 2019 03:17:03 +0530	[thread overview]
Message-ID: <854db2cf8145d9635249c95584d9a91fd774a229.1567889743.git.jrdr.linux@gmail.com> (raw)
In-Reply-To: <cover.1567889743.git.jrdr.linux@gmail.com>
In-Reply-To: <cover.1567889743.git.jrdr.linux@gmail.com>

__online_page_set_limits() is a dummy function and an extra call
to this function can be avoided.
