[PATCH] sigio: cleanup, don't take tasklist twice
The only user of send_sigio_to_task() already holds tasklist_lock, so it is better not to send the signal via send_group_sig_info() (which takes tasklist recursively) but use group_send_sig_info(). The same change in send_sigurg()->send_sigurg_to_task(). Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Cc: "Paul E.
