Kernelnewbies Digest, Vol 77, Issue 7

Wed Apr 12 06:29:53 EDT 2017

Hi Tran Ly Vu,

> How exactly do i start to contribute to linux community, i.e fix bug, etc

Below are my suggestions:

(1) Select a module which you are interested;
(2) Dive into the source code; subscribe the related mailing list and
concentrate on the news& updates of this module;
(3) After you are familiar with this module, you can take part in it: add
feature, fix bug, etc.

Best Regards
Nan Xiao
