How to get kernel header from my kernel source tree?

How to get kernel header from my kernel source tree?

[tianlilai]

Hi,Everyone:
I have updated the kernel from v2.6.32 to v2.6.36 using my kernel source 
tree(v2.6.36). so I must provide the new kernel header  to the 
developers of the device driver. How can I get the kernel header from my 
kernel source tree which the version is v2.6.36?

Thanks very much!

What "device driver developers"?  A Linux kernel driver is part of the
whole kernel image, you can't provide just header files to them, that
will not work at all as they can't build something that way, they need
the whole kernel source tree.

And 2.6.36 is very old, please just download the latest kernel release
from kernel.org and point the developers at that as well.

Do yourself and your developers a great service, and do the
following:

1) Upgrade to v4.0 (recently released). 2.6.36 is almost 5 years old.

2) Get your driver module in-tree. This has several benefits:

a) You don't have to worry anymore about figuring out what kernel
APIs changed when you upgrade kernels - the person who changed the API
will fix your code for you.

b) You can get out of the software distribution business totally. Just
ship the device, put a "Works with Linux 4.1 and later!" on the box, and
you don't need to worry about providing the driver, the user will get it
from their Linux distributor.

c) I'm sure Greg KH has a few other good reasons I can't remember because
I haven't had my morning caffeine.

Greg KH is the person to talk to about how to get your driver in-tree....
