All,
I'm trying to patch in a new module for my testing.
Out of curiosity, if it's a module, can't you just create a KMP?

I'm trying to package up the ext4 snapshot extension. A couple of the GSoC slots relate to snapshots and I'd like them to have ext4 snapshots to work with. My understanding is that for 2.6.38 the patch is still a little intrusive on the core ext4 driver and can't be fully a KMP., or if it is a KMP it requires some extra userspace tool patches to work right. My current assumption / working theory is that compiling a custom kernel as a package is easier then fixing the userspace issues. When 2.6.39 comes out, it is supposed to have the core patches in mainline, and the snapshot function can be a KMP per the design. That is with a 2.6.39 kernel + ext4 snapshot KMP, minimal userspace patches are needed to make it work. A 2.6.39 ext4-snapshot patch doesn't yet exist per my understanding. They are waiting to create it until after .39 is released. Then in 2.6.40, the ext4-snapshot team is hoping their code is in mainline. A lot of the patches have been sent to Ted Tso (ext4 maintainer) for review, but I haven't seen any major feedback, so I don't know how realistic that is. 2.6.41 may be a more realistic scenario for vanilla kernel inclusion.
