Subject: [GIT PULL] sched_ext: Changes for v6.20
Date: Mon, 09 Feb 2026 09:32:56 -1000 [thread overview]

Hi, Linus.
The following changes since commit ccaeeb585c7c2a0ac67ee1af9acb4d1411dc409e:
sched_ext: Use the resched_cpu() to replace resched_curr() in the bypass_lb_node() (2025-12-22 17:51:51 -1000)

selftests/sched_ext: Fix init_enable_count flakiness (2026-02-02 09:45:09 -1000)
----------------------------------------------------------------
sched_ext: Changes for v6.20
- Move C example schedulers back from the external scx repo to
tools/sched_ext as the authoritative source. scx_userland and scx_pair
are returning while scx_sdt (BPF arena-based task data management) is
new. These schedulers will be dropped from the external repo.
- Improve error reporting by adding scx_bpf_error() calls when DSQ
creation fails across all in-tree schedulers.
- Avoid redundant irq_work_queue() calls in destroy_dsq() by only
queueing when llist_add() indicates an empty list.
- Fix flaky init_enable_count selftest by properly synchronizing
pre-forked children using a pipe instead of sleep().
----------------------------------------------------------------
