Is there a way to make > it happen that both mainline and earlier trees can have this fix? Normally, bug fixes should first be submitted to the mainline kernel (also known as Linus's tree). If you use the "Fixes" and "CC-stable" tags, the patch will be automatically picked up for the appropriate stable kernels. If the patch does not apply to any stable kernel that you want it to be there, you can then post a back-ported patch to the stable mailing list. When doing so, it's better to include the following information: - The mainline commit ID of the back-ported patch. - The versions of the stable kernel(s) to which you want the back-ported patch to be applied. Hope this helps.
