Merge tag 'sched_ext-for-6.12-rc7-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext fix from Tejun Heo:
"One more fix for v6.12-rc7
ops.cpu_acquire() was being invoked with the wrong kfunc mask allowing
the operation to call kfuncs which shouldn't be allowed. Fix it by
using SCX_KF_REST instead, which is trivial and low risk"
* tag 'sched_ext-for-6.12-rc7-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext:
