xfs: test setting XFS BMBT fields in xfs_db
Test the setting of the XFS BMBT fields via xfs_db. Runs through the valid bit values for each field and tests an illegal value. [dchinner: added _require_xfs_mkfs_crc and turned off crcs so that the test doesn't just fail on CRC enabled test runs.] [dchinner: added hex block values to check they don't get endian swapped.] Signed-off-by: Mark Tinguely <tinguely@sgi.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>

# Test the xfs_db write of the XFS BMBT entries. For each XFS BMBT field,
|
||||
# write the value 0, each bit and finally the entry beyond the maximum legal
|
||||
# value. Also makes sure a core write and hex input still work.
