NAME
     brelse - return a buffer to the system's free list

SYNOPSIS
     #include <sys/types.h>

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

   Arguments
     bp	       Pointer to the buffer header structure.

DESCRIPTION
     The brelse function returns the buffer specified by bp to the system's
     buffer free list.	If there were any processes waiting for this specific
     buffer to become free, or for any buffer to become available on the free
     list, one is awakened.

   Return Values
     None

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
     Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

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