Date: Thu, 11 Feb 2016 21:50:26 +0530 [thread overview]
Message-ID: <1455207626-35488-7-git-send-email-sunil.kovvuri@gmail.com> (raw)
In-Reply-To: <1455207626-35488-1-git-send-email-sunil.kovvuri@gmail.com>
From: Sunil Goutham <sgoutham@cavium.com>
Allocate higher order pages when pagesize is small, this will
reduce number of calls to page allocator and wastage of memory.
