Linux kernel maintainers

"This document is mailed to lkml regularly and will be modified
whenever new victim wishes to be listed in it or someone can
no longer devote his time to maintainer work."

So, you are new to Linux kernel hacking and want to submit a kernel bug
report or a patch but don't know how to do it and _where_ to report it?
Then save this file for future reference.

Preparing bug report:
Compile problems: report GCC output and result of "grep '^CONFIG_' .config"
Oops: decode it with ksymoops.
Unkillable process: Alt-SysRq-T and ksymoops relevant part.
Yes it means you should have ksymoops installed and tested,
which is easy to get wrong. I've done that too often.

More info in the FAQ at http://www.tux.org/lkml/

Sending bug report/patch:
* Some device drivers have active developers, try to contact them first.
* Otherwise find a subsystem maintainer to which your report pertains
  and send report to his address.
* Small fixes and device driver updates are best directed to subsystem
  maintainers and "small bits" integrators.
* It never hurts to CC: Linux kernel mailing list, but without specific
  maintainer address in To: field there is high probability that your
  patch won't be noticed. You have been warned.
* Do not send it to all addresses at once! This will annoy lots of people
  and isn't useful at all. It's a spam.
* Do NOT send small fixes to Linus, he just can't handle _everything_.
  He will eventually receive it from maintainers/integrators, send it
  their way.
* If your patch is something big and new, announce it on lkml and try
  to attract testers. After it has been tested and discussed, you can
  expect Linus to consider inclusion in mainline.

Dave Jones  [5 feb 2002]
	I collect various bits and pieces for inclusion in 2.5,
	espesially small and trivial ones and driver updates. Do not bother

	are proved to be worthy.

Linus Torvalds  [5 feb 2002]
	Do not send anything to me unless it is for 2.5, well tested,
	discussed on lkml and is used by significant number of people.
	In general it is a bad idea to send me small fixes and driver
	updates, send them to subsystem maintainers and/or
	"small stuff" integrator (currently Dave Jones ,
	see his entry). Sorry, I can't do everything.

Marcelo Tosatti  [5 feb 2002]
	Do not send anything to me unless it is for 2.4 and well tested.
	If you are sending me small fixes and driver updates, send
	a copy to subsystem maintainers and/or "small stuff" integrators:
	- Alan Cox ,
	- Rusty Russell .

Rusty Russell  [5 feb 2002]
	> Here are some cleanups of whitespace in .....
	Want me to add this to the trivial patch collection for tracking?
	If so just send (or cc:) it to trivial@rustcorp.com.au.
