biofini - uninitialize a buffer structure
#include <sys/ddi.h>

void biofini(struct buf *bp);
illumos DDI specific (illumos DDI).
bp
Pointer to the buffer header structure.
The biofini() function uninitializes a buf(9S) structure. If a
buffer structure has been allocated and initialized using
kmem_alloc(9F) and bioinit(9F) it needs to be uninitialized
using biofini() before calling kmem_free(9F). It is not
necessary to call biofini() before freeing a buffer structure using
freerbuf(9F) because freerbuf() will call biofini()
directly.
The biofini() function can be called from any context.
Example 1 Using biofini()
struct buf *bp = kmem_alloc(biosize(), KM_SLEEP);
bioinit(bp);
/* use buffer */
biofini(bp);
kmem_free(bp, biosize());
