Summary
bpf: Send signals asynchronously if !preemptible
Details

In the Linux kernel, the following vulnerability has been resolved:

bpf: Send signals asynchronously if !preemptible

BPF programs can execute in all kinds of contexts and when a program running in a non-preemptible context uses the bpfsendsignal() kfunc, it will cause issues because this kfunc can sleep. Change irqs_disabled() to !preemptible().
