Add tracepoints for operations specific to zoned block devices. These tracepoints are also the foundation for adding zoned block device support to blktrace, which will be sent in a follow up. But even without the immediate support for ZBD operations in blktrace, these tracepoints have prooven to be effective in debugging issues with filesystems on zoned block devices.
