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.
Changes from v5:
* Split patch 3
* Update commit message
* Add MAX_STRUCT_PAGE_SIZE with value 64 and use that when allocating reserve
block
* Add BUILD_BUG_ON if we find sizeof(struct page) > 64
