Subject: [PATCH 5/9] libfrog: store more inode and block geometry in struct xfs_fd
Date: Thu, 29 Aug 2019 21:20:57 -0700	[thread overview]
Message-ID: <156713885704.386621.8085538826991730094.stgit@magnolia> (raw)
In-Reply-To: <156713882070.386621.8501281965010809034.stgit@magnolia>

From: Darrick J. Wong <darrick.wong@oracle.com>

Move the extra AG geometry fields out of scrub and into the libfrog code
so that we can consolidate the geoemtry code in one place.
