Subject: [PATCH] Consider namespace with size as active namespace
Date: Wed,  7 Aug 2019 10:09:15 +0530	[thread overview]
Message-ID: <20190807043915.30239-1-aneesh.kumar@linux.ibm.com> (raw)

This enables us to mark a namespace as disabled due to pfn_sb
mismatch. We have pending kernel patches at that will mark the
namespace disabled when the PAGE_SIZE or struct page size didn't
match with the value stored in pfn_sb.

We need to make sure we don't use this disabled namespace as seed namespace
for new namespace creation.
