Subjectlk 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.

If you want your entry added/updated/removed, contact me.

BTW, requests to move your entry to the top of the list
without actually changing the text are fine too: that
will indicate that entry is not outdated, so don't be shy ;-)

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?

Preparing bug report:
*** Remember: bad/incomplete bug report ONLY wastes bandwidth! ***
How To Ask Questions The Smart Way:
Anybody who has written software for public use will
probably have received at least one bad bug report.
Reports that say nothing ("It doesn't work!");
reports that make no sense; reports that don't give
enough information; reports that give wrong information.
How to Report Bugs Effectively:
Before asking a technical question by email, or in
a newsgroup, or on a website chat board, do the following:
* Try to find an answer by searching the Web.
* Try to find an answer by reading the manual.
* Try to find an answer by reading a FAQ.
* Try to find an answer by inspection or experimentation.
* Try to find an answer by reading the source code.
Compile problems: report GCC output and result of
"grep '^CONFIG_' .config"
Oops: decode it with ksymoops (or use 2.5 with kksymoops enabled ;).
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.

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.

I'm a maintainer for the Linux Test Project and it would be nice
if people knew to send their test programs, etc. to me. I see
a lot of them flying around on lkml and try to catch them when
I can, but it's a lot to keep up with. It would be even better
if people just knew to send them our way so we could clean
them up and put them in LTP for regression testing.

I work on the frame buffer subsystem, the m68k port (Amiga part),

Unfortunately I barely have spare time to really work on these
things. My job is not Linux-related (so far :-). I can not
promise anything about my maintainership performance.

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:
