Hi all,

Im fairly new to linux kernel and would like to start with some staging work (seems like the best way to start).
Basically what i would like to know is which tree should i clone for this? My understanding is that one should never work directly on top of the mainline tree, instead (for this case) on top of the linux staging tree. The same goes, for example, for USB subsystem development in which case i should just clone the usb development tree (and the same for all subsystems).

Is my understanding correct?

Thank you in advance!

Yes it is, make sure you work off of the correct branch as well.  For
the staging tree, working off of the staging-next is best.

thanks and good luck!

This would be my next question. Regarding the linux-next tree, the same as i wrote before also applies? So, I should not work directly in the linux-next tree but instead in the correspondent branch (subsystem-next) of the specific subsystem I'm working on?

You can use linux-next just fine, as it includes the staging-next
branch, along with all other subsystem's development trees.

Just be careful, linux-next rebases every day, you might have a harder
time doing development on it if you don't really know what you are doing
with git.

hope this helps,

The tree you are after is Greg's staging tree. You can find it here.

https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/

As Greg already said, the branch of that tree you want is
staging-next, also you may like to check your patches apply to the
staging-testing branch before submitting them.

Good luck,
Tobin.
