* reads and writes. When fallocate/fpunch calls are disabled, they are
- * converted to OP_SKIPPED. Hence OP_SKIPPED needs to have a number higher than
- * the operation selction matrix, as does the OP_CLOSEOPEN which is an
- * operation modifier rather than an operation in itself.

*
* Because of the "lite" version, we also need to have different "maximum
* operation" defines to allow the ops to be selected correctly based on the
