Hi Jeff,

Sorry for bothering you.  Could you please review this patch, or give me
some feedbacks.  If this patch can be applied, I can rebase it to the
lastest version of mainline kernel.  Thank you.

+int libata_fua = 1;

I guess it can be enabled after LOTS of testing of various drives out
there, which shows that no current drives have issues with FUA anymore,
and after building a black-list of devices which misbehave.  It is quite
a big project, I think.  But what it gives us in return?

(I've no idea if this is the right answer, speaking of myself only)

Thanks for the reply.  Indeed it is quite a big project but we enable
FUA feature for SAS disk.  Is there any differences?

Regards,
Zheng
