This has been addressed by systemtap git commit e94d0e3deb34e684ca83573d7d2bc9b382db2427 Have the scsi tapset support newer kernels struct scsi_cmnd The linux kernel commit 2266a2def97ce11ec removed the request field from struct scsi_cmnd. The scsi tapset needed to test whether the request field is available. If request field is not available, use the linux kernels helper function scsi_cmd_to_rq to get a value for request.
