ext4: support GETFSMAP ioctls
Support the GETFSMAP ioctls so that we can use the xfs free space management tools to probe ext4 as well. Note that this is a partial implementation -- we only report fixed-location metadata and free space; everything else is reported as "unknown". Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
