biodone - General: Indicates that block I/O is complete
struct buf *bp );
Specifies a pointer to a buf structure. This structure
contains information such as the binary status flags, the
major/minor device numbers, 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.
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 operation.
The routine panics if the buf structure is NULL.
