From: Darrick J. Wong <darrick.wong@xxxxxxxxxx> Refactor all the open-coded XFS_IOC_FSGEOMETRY queries into a single helper that we can use to standardize behaviors across mixed xfslibs versions. This is the prelude to introducing a new FSGEOMETRY version in 5.2 and needing to fix the (relatively few) client programs. Signed-off-by: Darrick J.
