The pid directories in /proc/ currently return the wrong hardlink count - 3,
when there are actually 4 : ".", "..", "fd", and "task".
This is easy to notice using find(1):
cd /proc/<pid>
find
In the output, you'll see a message similar to:
find: WARNING: Hard link count is wrong for .: this may be a bug in your
filesystem driver. Automatically turning on find's -noleaf option.
Earlier results may have failed to include directories that should have
been searched.

I also noticed that CONFIG_SECURITY can add a 5th: attr, and performed a
similar fix on the task directories too.

Attached is a new patch that solves the issue of getting valid credentials
into the LOGIN message. The current code was assuming that the audit context
had already been copied. This is not always the case for LOGIN messages.
To solve the problem, the patch passes the task struct to the function that
emits the message where it can get valid credentials.

Working on some code lately I've been getting huge values for "Cached".
The cause is that get_page_cache_size() is an approximate value, and for a
sufficiently small returned value of get_page_cache_size() the value
underflows.

iscsi/lvm2/multipath needs guaranteed protection from the oom-killer, so
make the magical value of -17 in /proc/<pid>/oom_adj defeat the oom-killer
altogether.
(akpm: we still need to document oom_adj and friends in
Documentation/filesystems/proc.txt!)

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
