scsi_free_consistent_buf - free a previously allocated SCSI DMA I/O buffer

#include <sys/scsi/scsi.h>
void scsi_free_consistent_buf(struct buf *bp);

bp
Pointer to the buf(9S) structure.

The scsi_free_consistent_buf() function frees a buffer header and consistent data buffer that was previously allocated using scsi_alloc_consistent_buf(9F).

The scsi_free_consistent_buf() function can be called from user, interrupt, or kernel context.

freerbuf(9F), scsi_alloc_consistent_buf(9F), buf(9S)

Writing Device Drivers

The scsi_free_consistent_buf() function will call freerbuf(9F) to free the buf(9S) that was allocated before or during the call to scsi_alloc_consistent_buf(9F).

If consistent memory is bound to a scsi_pkt(9S), the pkt should be destroyed before freeing the consistent memory.
