- More lifecycle fixes for the new sub-scheduler support: a failed enable could tear down a never-linked sub-scheduler in a way that races the root scheduler's disable and leads to a use-after-free, tasks that were not on the ext class could still get the enable callback, and a policy-rejection path silently rewrote a running task's scheduling policy instead of aborting the scheduler. - Scheduler enable/disable could deadlock with cgroup removal and a concurrent cgroup weight write through kernfs. Fixed by reordering lock acquisition. - Sync wakeups could leave the waker CPU incorrectly marked idle in the built-in idle-CPU tracking. - A selftest fix for sleeping tasks whose CPU affinity changes before wakeup. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCam/mog4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGe0NAQC2UrrXeSm97RTCv+5HBfom/8sjPdB2tiAwGiUt fUUQ+AD9FP30urJaoiALUiL+EGWpLFejwUCXNXlT+0kN2TiFxQM= =EuWf -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-7.2-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext fixes from Tejun Heo: - More lifecycle fixes for the new sub-scheduler support: a failed enable could tear down a never-linked sub-scheduler in a way that races the root scheduler's disable and leads to a use-after-free, tasks that were not on the ext class could still get the enable callback, and a policy-rejection path silently rewrote a running task's scheduling policy instead of aborting the scheduler. - Scheduler enable/disable could deadlock with cgroup removal and a concurrent cgroup weight write through kernfs.
