Subject: [PATCH 3/3] Test: SVM: Use ALIGN macro when aligning 'io_bitmap_area'
Date: Wed, 13 Jan 2021 02:46:33 +0000 [thread overview]
Message-ID: <20210113024633.8488-4-krish.sadhukhan@oracle.com> (raw)
In-Reply-To: <20210113024633.8488-1-krish.sadhukhan@oracle.com>
Since the macro is available and we already use it for MSR bitmap table, use
it for aligning IO bitmap table also.
