Subject: [PATCH linux-next] signal: Remove outdated __send_signal references in
 do_notify_parent

From: Fan Yu <fan.yu9@....com.cn>

The function __send_signal was renamed to __send_signal_locked in
commit 157cc18122b4 ("signal: Rename send_signal send_signal_locked"),
making the existing comments in do_notify_parent obsolete.

This patch removes these outdated references to maintain code clarity
and prevent confusion about the current implementation.
