[PATCH] [8/23] KGDB: Remove set but unused newPC
I'm not fully sure this is the correct fix, maybe this was a bug and newPC should really have a side effect. Jason?

[PATCH 1/1] VFS: introduce s_dirty accessors
From: Artem Bityutskiy <Artem.Bityutskiy(a)nokia.com> This patch introduces 3 VFS accessors: 'sb_mark_dirty()', 'sb_mark_clean()', and 'sb_is_dirty()'. They simply set 'sb->s_dirt' or test 'sb->s_dirt'. The plan is to make every FS use these accessors later instead of manipulating the 'sb->s_dirt' flag directly. ... 10 Jun 2010 07:47

Hi Linus, would it be possible to add the following patch to your tree. I'm trying to lessen amount of useless wake-ups in the kernel, and the 'sync_supers' thread if one of those kernel threads which wakes up every 5 seconds to (mostly) do nothing. This is still work in progress, but putting the below patch t... 10 Jun 2010 07:47
