I understand, thanks for letting me know!

Let me clarify / ask something: this series, for example, is composed as
a bunch of patches "centered" around the same idea, panic notifiers
improvements/fixes. But its patches belong to completely different
subsystems, like EFI/misc, architectures (alpha, parisc, arm), core
kernel code, etc.

What is the best way of getting this merged?
(a) Re-send individual patches with the respective Review/ACK tags to
the proper subsystem, or;

(b) Wait until the whole series is ACKed/Reviewed, and a single
maintainer (like you or Andrew, for example) would pick the whole series
and apply at once, even if it spans across multiple parts of the kernel?

Let me know what is the general preference of the kernel maintainers,
and I'll gladly follow that =)

Thanks,


Guilherme
