Let me guess, a lot of these are Power8 fixes ... This is a bit special this time around... we introduced some of the support in 3.9 and added a bunch in 3.10. We found bugs, it's brand new HW (not even final yet), and nobody out there has access to it nor will for a little while longer, so indeed nobody is going to use 3.10.0. I've been pushing back on a lot of it as a maintainer (which is why a lot of stuff ended up in 3.10 instead of 3.9), but granted probably not enough this time around. It's hard because the guys are getting a LOT of pressure in part because of distro schedules. As you are aware (and I mentioned in another email), some enterprise distros impose a very specific schedule for stuff to go upstream, and if that misses, well .... you are out of the game for years or lots of $ to convince them otherwise. Additionally, one of them has brain damaged rules about preserving kernel ABIs which prevents any significant addition for the entire lifetime of the distro major release. This is bad, this should not affect upstream in theory, but in practice it does because if we don't get into the damn enterprise distro, the whole exercise is pointless to begin with and we may as well not release the machines and stop the Linux business altogether. So I make compromises. I delay some stuff because it's really not ready, and I take some because it affects things like thread_struct layout which I know *WILL* break kABI and will be VERY hard to get back to the distro later, fully expecting that various bits of fixes are going to eventually trickle later on until it's ready for public consumption.
