SCSI_FREE_CONSISTENT_BUF(9F) Kernel Functions for Drivers
scsi_free_consistent_buf - free a previously allocated SCSI DMA I/O
buffer

void scsi_free_consistent_buf(struct buf *bp);
illumos DDI specific (illumos DDI).
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.
