Apparently it doesn't :
./io/xfs_io -c "fiemap 0 2k" ../xfstests-dev/trace.dat
../xfstests-dev/trace.dat:
0: [0..6095]: 18477056..18483151
the xfs_io is just v4.13.1 HEAD. One other things that comes to mind is
to play tricks with the xfs_io -c "help fiemap" invocation and parse the
first line. If the range param is supported then it will be present in
the one-line help if not, it won't be. Do you think that's acceptable ?
