About "how" -- ask K.Y. Srinivasan

Hyper-V admins need _worked_ Linux v3.4.X / v3.3.X / v3.2.X

Please, _fix_ errors related "use hv_storvsc instead of ata_piix to handle the IDE disks devices ( but not for the
CD-ROM)"


Thanks

Ok, I'll wait for KY to explain this.

Greg,

Clearly I cannot tell you anything about this that you don't know! Looking at the
rules for stable tree patches, this patch does not satisfy the requirement that
the patch fix a bug since we are changing the behavior here of the ata driver to
accommodate Hyper-V. I don't know how much flexibility you have here for
taking patches that improve the general usability of Linux in different
environments. All I can say is that It will be nice to have this patch in previous stable
releases.

Regards,

K. Y

Lots of things would be "nice", but as this doesn't meet the
stable_kernel_rules.txt rules, sorry, I can't take them.
