This looks like several tests use this setup. Factor?

These could really do with local variables to keep the verbosity
down and make it easy to change in future.
off=$((blksz * nr / 4))
iosz=$((blksz * nr / 2))
$XFS_IO_PROG -d -c "pwrite -S 0x63 -b $iosz $off $iosz" $testdir/file3
_pwrite_byte 0x63 $off $iosz $testdir/file3.chk
