scsi_destroy_pkt - free an allocated SCSI packet and its DMA resource
#include <sys/scsi/scsi.h> void scsi_destroy_pkt(struct scsi_pkt *pktp);
illumos DDI specific (illumos DDI).
pktp
The scsi_destroy_pkt() function releases all necessary resources, typically at the end of an I/O transfer. The data is synchronized to memory, then the DMA resources are deallocated and pktp is freed.
The scsi_destroy_pkt() function may be called from user, interrupt, or kernel context.
Example 1 Releasing resources
scsi_destroy_pkt(un->un_rqs);
tran_destroy_pkt(9E), scsi_init_pkt(9F), scsi_pkt(9S)
