Subject: [PATCH v3 4/6] mm/nvdimm: Use correct #defines instead of opencoding
Date: Tue, 4 Jun 2019 14:43:55 +0530 [thread overview]
Message-ID: <20190604091357.32213-4-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20190604091357.32213-1-aneesh.kumar@linux.ibm.com>
The nfpn related change is needed to fix the kernel message
"number of pfns truncated from 2617344 to 163584"
The change makes sure the nfpns stored in the superblock is right value.
