Google is just one user - but they have (so I hear) a large number
of machines.

I would hazard a guess that there are other users that feel the
same way - i.e. users with a large number of machines that move
onto new kernel versions from time to time.

These users want a stable kernel->user ABI - and Google has stated
quite clearly that "printk" doesn't meet their need. I think that
they would be happy with some other stable solution than mcelog,
but we might as well ask for their input before imposing something
on them.

Mike: would you like to join the conversation on how to report
errors - or nominate someone else to represent the Google point
of view?

-Tony
