  sched_ext: Use WRITE_ONCE() for the write side of scx_enable helper pointer (2026-03-09 06:08:26 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v7.0-rc3

- Fix data races flagged by KCSAN: add missing READ_ONCE()/WRITE_ONCE()
  annotations for lock-free accesses to module parameters and dsq->seq.

- Fix silent truncation of upper 32 enqueue flags (SCX_ENQ_PREEMPT and
  above) when passed through the int sched_class interface.

- Documentation updates: scheduling class precedence, task ownership
  state machine, example scheduler descriptions, config list cleanup.

- Selftest fix for format specifier and buffer length in
  file_write_long().
