The patch titled
Char: mxser_new, remove unused stuff
has been removed from the -mm tree. Its filename was
char-mxser_new-remove-unused-stuff.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Char: mxser_new, remove unused stuff
From: Jiri Slaby <jirislaby@xxxxxxxxx>
- nobody waits on close_wait
- ASYNC_SPLIT_TERMIOS is not set by anybody, so do not test this flag
- process session and pgrp are useless information
