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

DESCRIPTION
The brelse function returns the buffer specified by bp to the system's

USAGE
The buffer specified by bp must have been previously allocated by a call
to geteblk(D3) or ngeteblk(D3). brelse may not be called to release a
buffer which has been allocated by any other means.
Level

Driver-defined basic locks, read/write locks, and sleep locks may be held
across calls to this function.
