Subject: [ndctl PATCH v4 3/6] libcxl: return the partition alignment field in bytes
Date: Mon,  7 Feb 2022 15:10:17 -0800	[thread overview]
Message-ID: <fad634a7912265e87a8e7f3c3c9db21c1494d9ad.1644271559.git.alison.schofield@intel.com> (raw)
In-Reply-To: <cover.1644271559.git.alison.schofield@intel.com>

From: Alison Schofield <alison.schofield@intel.com>

Per the CXL specification, the partition alignment field reports
the alignment value in multiples of 256MB. In the libcxl API, values
for all capacity fields are defined to return bytes.

Update the partition alignment accessor to return bytes so that it
is in sync with other capacity related fields.
