Filtering pid_tgid is meaningless when the current task is preempted by an interrupt. To address this, introduce the bpf_in_interrupt kfunc, which allows BPF programs to determine whether they are executing in interrupt context. This enables programs to avoid applying pid_tgid filtering when running in such contexts. Signed-off-by: Leon Hwang <[email protected]>
