- This synchronizes scx repo to the sched_ext repo again.
- All schedulers including rust ones have proper backward compatibility.
- We're spraying Cargo dependency patches in each rust scheduler to pull in the latest libbpf*. Something to clean up futher.
Sync from kernel to receive new vmlinux.h and the updates to common headers. This includes the following updates: - scx_bpf_switch_all() is replaced by SCX_OPS_SWITCH_PARTIAL flag. - sched_ext_ops.exit_dump_len added to allow customizing dump buffer size. - scx_bpf_exit() added. - Common headers updated to provide backward compatibility in a way which hides most complexities from scheduler implementations. scx_simple, qmap, central and flatcg are updated accordingly. Other schedulers are broken for the moment.
Fix up the remaining C schedulers after the recent API and header updates. Also drop stray -p from usage help message from some schedulers.
Implement scx_utils::compat to match C's scx/compat.h and update scx_layered. Other rust scheds are still broken.
No need to keep them around.
- scx_utils bumped from 0.6.0 to 0.7.0. - Repo and rust schedulers get a PATCH level bump.
…h.crates-io sections New versions of libbpf-rs and libbpf-cargo are now available with all the needed features. Update the dependencies and drop the patch sections.

Synchronize stragglers. - Bug fix in __COMPAT_read_enum(). - A cosmetic difference in scx_qmap.bpf.c. - Stray 'p' when calling getopt() in scx_simple.c. After this the kernel tree and scx repo are in sync.
