Fiemap gained support for passing in optional offset len which denote the range requested, so this patch adds testcases for this functionality. Aditionally, a special "ranged" argument is added to the require_xfs_io_command which checks for the presence of fiemap range support.

# Test for the new ranged query functionality in xfs_io's fiemap command.
|
|
# This tests various combinations of hole + data layout being printed.
|
|
# Also the test used 16k holes to be compatible with 16k block filesystems
