Yes, or actually I hope the one who has been maintaining patches so far to 2.4 would comment on this.

The code from lk2-4 should work and compile with 2.4.9 too. The original 2.4.9's i2c drivers (video4linux) will fail to compile, or needs patch like the ones for 2.4.20 and 2.4.21-pre3 I posted. >From HEAD, I would only support the latest of 2.5. We can use tags like lk2-5-90 to note this is i2c as of 2.5.90, I see no point of supporting all of 2.5.54+ from HEAD, until 2.6 comes around. > If and only if we wanted to make another i2c release that was compatible for > kernels 2 4.9 - 2.4.20 (hopefullly not) would we branch again, at the > tag POST-2-4-9-KERNELS, and generate a release from that branch. Either that to use inc/dec_use refcounting, or create incremental patches to modify 2.4 tree i2c drivers for .owner. > For sensors we would do something similar, following your > instructions below...

There may not be need to branch sensors at all, as the dependency is to the .owner refcounting that applies to both 2.4 and 2.5 trees if our i2c lk2-4 is accepted. The tag LAST-PRE-2-4-X-KERNEL is to branch if we find severe problems we need to fix for 2.2 kernels. Hopefully not. I have got sensors .owner changes in my working directory. While at it, I have changed drivers to use module_init/exit, have removed a lot of #ifdef MODULE everywhere. And just generally break it. -- Ky?sti M?lkki kmalkki at cc.hut.fi
