Subject: [PATCH 1/1] MD:Update superblock when err == 0 in size_store
Date: Sun, 12 Jun 2016 17:18:00 +0800	[thread overview]
Message-ID: <1465723080-9375-1-git-send-email-xni@redhat.com> (raw)

Hi

This is a simple check before updating the superblock. It should update
the superblock when update_size return 0.

Regards
