Subject: [PATCH RFC 0/1] Document how to add a new syscall

Given that I've gotten some of the details wrong in the past (and I've
seen others do likewise), I thought it might be helpful to collate the
best practices for adding a new system call to the kernel.

Apologies for the wide circulation -- I've tried to include folk who've
recently added or proposed a system call, as they're most likely to
have opinions on:
 - whether this a useful addition to Documentation/
 - whether the details of the advice are correct and complete.

Shuah, is there anything more that should be added for the Testing
section in particular?

Thanks,
David

(With thanks to Andrew Morton for looking over an initial draft, and to
Michael Kerrisk for suggesting several clarifications and additions.)
