DESCRIPTION

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

CONTEXT

32       bioreset() can be called from any context.
