From 64e0cc38b69b8d43ab9793f50e4bb09cea0e6bb9 Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Sat, 5 Aug 2006 12:14:39 -0700 Subject: [PATCH] [PATCH] pSeries: hvsi char driver janitorial cleanup A set of tty line discipline cleanup patches were introduced before the dawn of time, in kernel version 2.4.21. This patch performs that cleanup for the hvsi driver. The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was originally written by Hollis Blanchard, who has delegated maintainership to me. So this my first and maybe only patch in this official new role, because this driver is otherwise bug-free :-) Alan: "Actually its also a bug fix, tty->ldisc should be locked by refcounting and the helpers do this for you."
