Subject: ITIMER_REAL: convert to use struct pid
X-Git-Tag: v2.6.25-rc1~206
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fea9d175545b38cb3e84569400419eb81bc90fa3;p=pandora-kernel.git

ITIMER_REAL: convert to use struct pid

signal_struct->tsk points to the ->group_leader and thus we have the nasty
code in de_thread() which has to change it and restart ->real_timer if the
leader is changed.

Use "struct pid *leader_pid" instead.  This also allows us to kill now
unneeded send_group_sig_info().
