Subject: [PATCH v2 4/4] Use page size as alignment value
Date: Thu, 25 Feb 2021 11:43:03 +0530	[thread overview]
Message-ID: <20210225061303.654267-4-santosh@fossix.org> (raw)
In-Reply-To: <20210225061303.654267-1-santosh@fossix.org>

The alignment sizes passed to ndctl in the tests are all hardcoded to 4k,
the default page size on x86. Change those to the default page size on that
architecture (sysconf/getconf). No functional changes otherwise.
