signal: Remove has_group_leader_pid (bbd40fc4) · Commits · 戴 / test

After the introduction of exchange_tids has_group_leader_pid is equivalent to thread_group_leader. After the last couple of cleanups has_group_leader_pid has no more callers. So remove the now unused and redundant has_group_leader_pid. Signed-off-by:
