Subject: [PATCH 15/16] xfs: xfs_fs_geometry returns a number of bytes to copy
Date: Fri, 3 Oct 2014 17:05:09 -0500 [thread overview]
Message-ID: <20141003220508.GO1865@sgi.com> (raw)
In-Reply-To: <20141003214758.GY1865@sgi.com>
From: Ben Myers <bpm@sgi.com>
The versioned xfs_fsop_geom_t will be of variable size. Make
xfs_fs_geometry return the number of bytes to copy out to userspace for
a given version of the structure.
