NAME
       biodone - General: Indicates that block I/O is complete

SYNOPSIS
       void biodone(
	       struct buf *bp );

ARGUMENTS
       Specifies  a  pointer to a buf structure.  This structure contains information such as the binary status flags, the major/minor device num-
       bers, and the address of the associated buffer. This buffer is always a special buffer header owned exclusively by the device for  handling
       I/O requests.

DESCRIPTION
       The  biodone  routine is called after an I/O operation to mark the buf structure as completed. It sets the b_flags member to B_SWAP, B_UBC,
       or B_ASYNC to indicate the type of I/O operation that has completed. Other members may be set as well, depending on the type of I/O  opera-
       tion.

CAUTIONS
       The routine panics if the buf structure is NULL.

RETURN VALUES
       None
