 Well, I have worked with Linux (and other free software projects) both as 
a code contributor and a reviewer/maintainer for some 25 years now and I 
know very well what the responsibilities are for both sides.

 And surely I have not asked for this particular patch set to be accepted 
without a review, but for assistance with the review.  I do hope I have 
made it clear enough in my message.

 The incentive for my proposal was the lack of good identification given 
it the kernel log: <https://pastebin.com/QXaUsCV4>, which is generally the 
only source that can be reliably referred via Internet searches; people do 
not publish their sysfs data.

 Said log was posted in the course of investigating an IRQ routing bug: 
<https://lore.kernel.org/r/60B24AC2.9050505@gmail.com>, 
<https://lore.kernel.org/r/60E726E2.2050104@gmail.com/>, and ultimately I 
have sorted the problem in a generic way that does not require a DMI quirk 
to be added; cf.:
<https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=ac7cd5e16df8696c39e29b03dfedf069a025b822>, 
<https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=5a0e5fa957db79177baa851d687b6f6aa5a0be96>, 
<https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=fe62bc23620fa027162e05594a610ff5e556496a>.

 However that does not mean we should continue logging crappy data.  This 
is because evidently people still want to use these systems, and next time 
we may not be so lucky as to avoid relying on DMI data, however limited.

 We all are busy, aren't we?  If you cannot perform your maintainer's 
duties for a given subsystem in a timely manner, not even to send a note 
that the waiting queue is long, then perhaps you should reconsider if you 
can afford the post?

 NB I have fixed Nikolai's problem even though I am not a maintainer for 
the relevant subsystem, so I have no obligation of any kind there, unlike 
actual maintainers.

 Whatever your priorities are it does mean exactly what I have implied in 
my message: that evidence shows the maintenance of the DMI subsystem does 
not work.

 Therefore I have referred to the chief maintainer of the project, the 
only sensible action given the state of affairs.  This is because as you 
have correctly observed this patch set has been already pinged too many 
times and (as a general life rule) you can't expect a different outcome 
from the same action repeated, so if things repeatedly do not work, then 
you need to try something else.

 Please refer to this paragraph:

"Once upon a time, patches used to disappear into the void without comment,
but the development process works more smoothly than that now.  You should
receive comments within a week or so; if that does not happen, make sure
that you have sent your patches to the right place.  Wait for a minimum of
one week before resubmitting or pinging reviewers - possibly longer during
busy times like merge windows."

in Documentation/process/submitting-patches.rst too, which I think gives a 
good overview of the practices and timelines expected from submitters and 
maintainers.  I have to admit that I waited a bit longer than a week 
before I started pinging though.

 In most free software projects the general/head maintainter(s) step in by 
themselves with overdue reviews if subsystem-specific ones are too busy to 
handle submissions in a timely manner, however I do realise Linux has 
grown too large for this approach to be feasible.

 Thank you for your time spent to write your reply.

 NB it is generally accepted that publishing messages sent privately is 
inappropriate without obtaining consent first from the involved parties.  
Please assume my previous consent for your posting on this occasion 
though.
