NAME
scsi_free_consistent_buf - free a previously allocated SCSI DMA I/O buffer
SYNOPSIS
#include <sys/scsi/scsi.h> void scsi_free_consistent_buf(struct buf *bp);
INTERFACE LEVEL
illumos DDI specific (illumos DDI).
PARAMETERS
bp
Pointer to the buf(9S) structure.
DESCRIPTION
The scsi_free_consistent_buf() function frees a buffer header and
consistent data buffer that was previously allocated using
scsi_alloc_consistent_buf(9F).
CONTEXT
The scsi_free_consistent_buf() function can be called from user,
interrupt, or kernel context.
SEE ALSO
freerbuf (9F), scsi_alloc_consistent_buf (9F), buf (9S) Writing Device Drivers
WARNING
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.
