Subject: [PATCH 5/5 v3] Test: SVM: Use ALIGN macro when aligning 'io_bitmap_area'
Date: Tue,  2 Feb 2021 19:40:35 -0500	[thread overview]
Message-ID: <20210203004035.101292-6-krish.sadhukhan@oracle.com> (raw)
In-Reply-To: <20210203004035.101292-1-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.
