Subject: [PATCH] md: don't impose the MD_SB_DISKS limit on arrays without metadata.
Date: Wed, 01 Mar 2017 07:31:28 +1100	[thread overview]
Message-ID: <87k28aoy5b.fsf@notabene.neil.brown.name> (raw)

[-- Attachment #1: Type: text/plain, Size: 834 bytes --]


These arrays, created with "mdadm --build" don't benefit from a limit.
The default will be used, which is '0' and is interpreted as "don't
impose a limit".
