Subject: [PATCH bpf-next v3 0/2] Implement mechanism to signal other threads
This set implements a kfunc called bpf_send_signal_task() 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 v3:
v2: https://lore.kernel.org/all/20240926115328.105634-1-puranjay@kernel.org/
- make the cookie u64 instead of int.
- re use code from bpf_send_signal_common
Changes in v2:
v1: https://lore.kernel.org/bpf/20240724113944.75977-1-puranjay@kernel.org/
- Convert to a kfunc
- Add mechanism to send a cookie with the signal.
