Hello,

Please excuse me if I haven't done my home work, but...

Why isn't kernel-headers made explicitly from the kernel project, even though its patch-set is dealing with ABI ?

because that causes major issues with OBS rebuilds. kernel-headers change causes glibc to rebuild (and then the OS). ... this would limit the rate at which we can do kernel updates


I have pondered the issue with the few example headers we have with V4L2/MediaController API changes. So, are we currently utilizing backported drivers and stuff, but tend to think that kernel stays ABI compatible with older upstream version ?

the other reason is that we ONLY want to ship the OFFICIAL ABI to applications, not an "abi" that comes from random patches added to the kernel.

2. request kernel committers to commit kernel-headers too (and consider how this will stay in sync)

no to either;
the only request we'll take is "can you move kernel-headers to a new upstream version".. if you get your ABI change accepted by Linus and then into a release, we can get it into kernel-headers.
