I don't know any other real user of this struct than the mcelog and the
mce test suite.  In other words, I expected that you (Huang and Andi) are
only users who may be confused by this kind of change.

I believe this exported struct is not well defined.
At least I could not figure out why we need to pass the value of .finished
from/to user space.

However, this change is not urgent thing.  I'll put aside this for now.


Thanks,
H.Seto
