From f96a795d4f6a8a13abe4b0d3c5d1c28ea8d7ce4b Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 28 Mar 2006 16:11:01 -0800 Subject: [PATCH] do_tty_hangup: use group_send_sig_info not send_group_sig_info We already have the tasklist_lock so there is no need for us to reacquire it with send_group_sig_info. reader/writer locks allow multiple readers and thus recursion so the old code was ok just wastful.
