Subject: [PATCH 24/37] db: verify and calculate dquot CRCs
Date: Wed,  6 Nov 2013 12:07:10 +1100	[thread overview]
Message-ID: <1383700043-32305-25-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1383700043-32305-1-git-send-email-david@fromorbit.com>

When we set the current Io cursor to point at a dquot block, verify
that the dquot CRC is intact. And prior to writing such an IO
cursor, calculate the dquot CRC.
