The \fBscsi_free_consistent_buf()\fR function frees a buffer header and
consistent data buffer that was previously allocated using
\fBscsi_alloc_consistent_buf\fR(9F).
.SH CONTEXT

The \fBscsi_free_consistent_buf()\fR function can be called from user,
interrupt, or kernel context.
.SH SEE ALSO

.SH WARNING
.sp
.LP
The \fBscsi_free_consistent_buf()\fR function will call \fBfreerbuf\fR(9F) to
free the \fBbuf\fR(9S) that was allocated before or during the call to
\fBscsi_alloc_consistent_buf\fR(9F).
.sp
.LP
If consistent memory is bound to a \fBscsi_pkt\fR(9S), the pkt should be
destroyed before freeing the consistent memory.
