As before, if a SEC queue is at the 'fake busy' status,
the request with a 'fake busy' flag will be sent into hardware
and the sending function returns busy. After the request is
finished, SEC driver's call back will identify the 'fake busy' flag,
and notifies the user that hardware is not busy now by calling
user's call back function.

Now, a request sent into busy hardware will be cached in the
SEC queue's backlog, return '-EBUSY' to user.
After the request being finished, the cached requests will
be processed in the call back function. to notify the
corresponding user that SEC queue can process more requests.

Why does this driver not take MAY_BACKLOG into account?

Cheers,

OK, I will apply MAY_BACKLOG in the next version soon.

thanks,
