Thanks for such detailed information. Now I have a subject what I should think about. And yes, I'll chose my own way :) 22.12.2016, 20:26, "valdis.kletnieks@vt.edu" <valdis.kletnieks@vt.edu>:

 I just thought that may be it will be quicker to start to develop for kernel.

The quickest way to start will depend on why you're thinking of doing kernel development at all.

Did your boss just tell you that you have 13 weeks to ship a Linux driver for your company's new USB widget?

Do you have a device that Linux doesn't support? Do you have a device that Linux *claims* to support, but it doesn't work quite right? Do you have a device that used to work, but broke recently?

(And yes, the approaches for the 3 are different)

Do you have a deep desire to do something specific? "Wow, filesystems are really cool"? "I want to push my laptop to the limits"? Something else?

Do you just want to give back to the community? If so, skip developing and just build and run a new linux-next kernel once a week. Lots easier to get started, and we have plenty of developers - but lots fewer people actually testing the 600,000 lines of new code every release. And how do I know there's less testers than developers? Because if we had as many testers, I wouldn't personally trip over an average of 3 to 5 bugs in linux-next per release cycle.

Did you think it would be a babe magnet? Or looking for something to put on your resume?

All these have different paths....

(And here's the quick hint on how to get started with linux-next:

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git (the clone created a subdirectory, so cd to it for the following) $ cd linux $ git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git $ git fetch linux-next $ git fetch --tags linux-next ... # later on $ git remote update ...

Once a week, do a 'git remote update' and build/install/run the new kernel. If anything explodes, send an email to linux-kernel@vger.kernel.org

And yes, it really *is* that easy.
