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. Thanks, David (With thanks to Andrew Morton for looking over an initial draft, and to Michael Kerrisk for suggesting several clarifications and additions.) Changes since v1: - added paragraph on build requirements to Testing section [Shuah Khan, Peter Zijlstra] - various text clarifications [Kees Cook] - added Reviewed-by markers David Drysdale (1): Documentation: describe how to add a system call Documentation/adding-syscalls.txt | 463 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 463 insertions(+) create mode 100644 Documentation/adding-syscalls.txt -- 2.2.0.rc0.207.ga3a616c
