Hi,

I have the following queries regarding back porting of up-streamed Linux kernel 
driver:

Suppose a new driver is added to Linux mainline in release 4.2, will the 
developer who added new driver to the mainline need to submit the changes for 
back porting to the backports git?

Or will the backports project team be doing the back porting of the new driver?

Guess the one with most incentive will do it.


 From the following page https://backports.wiki.kernel.org/index.php/Main_Page

"Current versions of backports support all mainline kernels starting with version 
3.0, for kernel versions older than 3.0 please use backports-3.14, which supports all 
kernel versions back to 2.6.26."

Suppose we have release backports-4.2 and new driver has been backported. Will 
it have support only till kernel version 3.0. Suppose if the new driver needs 
to be supported in version 2.6.32 what is the process followed?

That is a problem that backports can not solve. So you could manually backport your new driver into the backport-3.14 tarball to minimize your effort.
