Restructure scheds folder names - combine c and kernel-examples as it's confusing to have both - rename 'rust-user' and 'c-user' to just 'rust' and 'c', which is simpler - update and fix sync-to-kernel.sh 2023-12-17 20:01:40 +00:00			`c_scheds = ['scx_simple', 'scx_qmap', 'scx_central', 'scx_pair', 'scx_flatcg', 'scx_userland', 'scx_nest']`

scx: Add CI action that builds schedulers for PRs When Ubuntu ships with sched_ext, we can also maybe test loading the schedulers (not sure if the runners can run as root though). For now, we should at least have a CI job that lets us verify that the schedulers can _build_. To that end, this patch adds a basic CI action that builds the schedulers. As is, this is a bit brittle in that we're having to manually download and install a few dependencies. I don't see a better way for now without hosting our own runners with our own containers, but that's a bigger investment. For now, hopefully this will get us _some_ coverage.

build: introduce kernel_headers build option If we try to cross-build scx on builders with older versions of system's linux headers (such as those provided by linux-libc-headers in older releases of Ubuntu), we may hit build failures, due to the different kernel ABI, such as: error: invalid use of undefined type ‘struct btf_enum64’ To address this, introduce a new build option called "kernel_headers" that allows to specify a custom path for the kernel headers required during the build process.
