You can ask for those bugfixes to get backported to the stable/longterm kernel tree, see Documentation/stable_kernel_rules.txt for how to do this properly. > Just out of curiosity. > > Is there any rule about update period in long-term kernel? > I mean how often you release long-term kernel.

No, the LTSI kernel work has been slow due to the lack of time on my part lately. > If I get the answer on above two quesion, I can expect later what LTSI kernel > version include feature I need. > > Another question. > For example, There is A feature in mainline and A has no problem but > someone invents new wheel "B" which is better than A so it replace A totally > in recent mainline.

No, you can submit the same patches for the LTSI kernel as well, they will probably be accepted as the rules are much more "loose" for the LTSI tree compared to the normal stable/longterm kernel rules. Which is the primary reason it is around. Hope this helps, greg k-h -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
