This set implements a kfunc called bpf_send_signal_remote() that is similar to sigqueue() as it can send a signal along with a cookie to a thread or thread group. The send_signal selftest has been updated to also test this new kfunc under all contexts. Changes in v2: v1: https://lore.kernel.org/bpf/20240724113944.75977-1-puranjay@xxxxxxxxxx/ - Convert to a kfunc - Add mechanism to send a cookie with the signal.
