Subject: xfs: hoist xfs_fs_geometry to libxfs
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c368ebcd4cc3bbc08602adce083ad3cc76a15258;p=openwrt%2Fstaging%2Fblogic.git

xfs: hoist xfs_fs_geometry to libxfs

Move xfs_fs_geometry to libxfs so that we can clean up the fs geometry
reporting in xfsprogs.
