The MKFS_OPTIONS env. var. can be defined with the correct options for the associated fs being tested. That eliminates the need to loop and for the fs-specific _scratch_mkfs calls above. > + _scratch_mount >> $seqres.full 2>&1 > + > + # Write file > + $XFS_IO_PROG -f -c "pwrite 0 $length" -c fsync $testfile > /dev/null > + > + > + # Insert alternate blocks Trailing space in the above comment. > + for (( j=0; j < $(($BLOCKS/2)); j++ )); do > + offset=$((($j*$BSIZE)*2)) > + $XFS_IO_PROG -c "finsert $offset $BSIZE" $testfile > /dev/null > + done > + > + # Check if 100 extents are present > + $XFS_IO_PROG -c "fiemap -v" $testfile | grep "^ *[0-9]*:" |wc -l > + > + _check_scratch_fs > + if [ $? -ne 0 ]; then > + status=1 > + exit > + fi > + > + # Collapse alternate blocks ... and here as well. > + for (( j=0; j < $(($BLOCKS/2)); j++ )); do > + offset=$((($j*$BSIZE))) > + $XFS_IO_PROG -c "fcollapse $offset $BSIZE" $testfile > /dev/null > + done > + > + # Check if 1 extents are present > + $XFS_IO_PROG -c "fiemap -v" $testfile | grep "^ *[0-9]*:" |wc -l > + > + _check_scratch_fs > + if [ $? -ne 0 ]; then > + status=1 > + exit > + fi > + Maybe create a copy of the original file before we run through the insert and collapse sequence and cmp the files here as a last step?
