Subject: [PATCH v6 0/12] KGDB/KDB FIQ (NMI) debugger
Date: Tue, 11 Sep 2012 02:30:43 -0700 [thread overview]
Message-ID: <20120911093042.GA12471@lizard> (raw)
Hi all,
Here is a new revision, mostly tty reworks. The new tty_port stuff is a
bliss: no more per-driver mutex, no more counting for open(),
well-separated initialization callbacks (I hope I got them right :-).
But since I now use a lot of new tty_port stuff, I had to rebase the
patch set on top of tty-next, so there's no point in cherry-picking
anymore.
So, in v6:
- Converted the NMI tty driver to use tty_port helpers, per Alan Cox's
suggestions;
- In uart's poll_init callback fixed a race, spotted by Alan;
- Use test_bit instead of touching port->flags directly;
These patches can be found in the following repo (based on tty-next):
git://git.infradead.org/users/cbou/linux-nmi-kdb.git master
Old changelogs and rationale for these patches can be found here:
v1-v5: http://lkml.org/lkml/2012/9/10/2
Thanks,
