From 850d6fbe70c62a9792eac3e8ef34f2f09f209895 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sun, 8 Jan 2006 01:03:29 -0800 Subject: [PATCH] [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 Cc: "Paul E.
