Subject: [PATCH v5 0/4] Mark the namespace disabled on pfn superblock mismatch
Date: Fri, 9 Aug 2019 13:15:16 +0530 [thread overview]
Message-ID: <20190809074520.27115-1-aneesh.kumar@linux.ibm.com> (raw)
We add new members to pfn superblock (PAGE_SIZE and struct page size) in this series.
This is now checked while initializing the namespace. If we find a mismatch we mark
the namespace disabled.
This series also handle configs where hugepage support is not enabled by default.
This can result in different align restrictions for dax namespace. We mark the
dax namespace disabled if we find the alignment not supported.
Aneesh Kumar K.V (4):
nvdimm: Consider probe return -EOPNOTSUPP as success
mm/nvdimm: Add page size and struct page size to pfn superblock
mm/nvdimm: Use correct #defines instead of open coding
mm/nvdimm: Pick the right alignment default when creating dax devices
