Change find_new_reaper() to use for_each_thread() instead of deprecated while_each_thread(). We do not bother to check "thread != father" in the 1st loop, we can rely on PF_EXITING check. Note: this means the minor behavioural change: for_each_thread() starts from the group leader. But this should be fine, nobody should make any assumption about do_wait(__WNOTHREAD) when it comes to reparented tasks. And this can avoid the pointless reparenting to a short-living thread While zombie leaders are not that common. Signed-off-by:
