In the Linux kernel, the following vulnerability has been resolved:
bpf: Disable preemption in bpf_get_stackid
The get_perf_callchain call needs disabled preemption plus we need
it disabled as long as we access its returned trace entries buffer.
Note the bpf_get_stackid_pe function is executed already with
preemption disabled.
