Now that the sg version 4 interface is supported:
- with ioctl(SG_IO) for synchronous/blocking use
- with ioctl(SG_IOSUBMIT) and ioctl(SG_IORECEIVE) for
async/non-blocking use
Plus new ioctl(SG_IOSUBMIT_V3) and ioctl(SG_IORECEIVE_V3)
potentially replace write() and read() for the sg
version 3 interface. Bump major driver version number
from 3 to 4.
The main new feature is the removal of the fixed 16 element
array of requests per file descriptor. It is replaced by
two lists: one for active (inflight) requests and a free
list. Also sg_requests objects are not freed until the
owning file descriptor is closed; rather these objects
are re-used when multiple commands are sent to the same
file descriptor.
