These two tests call various fallocate modes on a file and compare the FIEMAP output to some golden output. Unfortunately, the golden output doesn't take into account the possibility that (on XFS) the files could be created on a realtime volume with a large rt extent size set. Under such a configuration, fpunch operations that are aligned to the fs block size but not the rt extent size simply result in those blocks being set to unwritten status. Unfortunately, the test expects holes and fails. Therefore, detect the situation and skip the tests. Signed-off-by: Darrick J.
