bioreset - reuse a private buffer header after I/O is complete

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

Pointer to the buf(9S) structure.

bioreset() is used by drivers that allocate private buffers with getrbuf(9F) or kmem_alloc(9F) and want to reuse them in multiple transfers before freeing them with freerbuf(9F) or kmem_free(9F). bioreset() resets the buffer header to the state it had when initially allocated by getrbuf() or initialized by bioinit(9F).

bioreset() can be called from any context.

bp must not describe a transfer in progress.
