Tejun Heo f261d0f037 Sync from kernel - 1edab907b57d
Sync from sched_ext/for-6.11 1edab907b57d ("sched_ext/scx_qmap: Pick idle
CPU for direct dispatch on !wakeup enqueues")

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext.git for-6.11

- cgroup support hasn't landed in the upstream kernel yet. This most likely
  will happen in a few weeks. For the time being, disable scx_flatcg,
  scx_pair and scx_mitosis.

- Compat macro for DSQ task iterator dropped. This is now a part of
  the baseline.

- scx_bpf_consume() isn't upstream yet. BPF interfacing side is still being
  discussed. Dropped example usage from tools/sched_ext. None of the
  practical schedulers use it, so this should be fine for now.

- scx_bpf_cpu_rq() added.

- AUTOATTACH workaround for newer libbpf versions added.

Meson

# the previous scheduler in the compile sequence
sched = []
# Since meson and cargo tries build in parallel, this can cause significant load
# when meson tries to launch N instances of cargo and cargo tries to compile N files
# in parallel (N*N compiler instances in total).
#
# To prevent this from happening, we try to force meson to build them sequentially
# by making the "current" scheduler depend on another scheduler.
# To add a new scheduler, assign the output of your custom_target to sched
# and add sched as a dependency to your custom_target. For example:
#
# sched = custom_target('scx_mysched',
# ...
# depends: [mydep, sched],
# build_always_stale: true)

#subdir('scx_mitosis') # Temporarily excluded until cgroup support lands in the kernel

subdir('scx_bpfland')
