Kostik Belousov 411b67b4b6 [PATCH] readv/writev syscalls are not checked by lsm
it seems that readv(2)/writev(2) syscalls do not call
file_permission callback. Looks like this is overlook.

I have filled the issue into redhat bugzilla as
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169433
and got the recommendation to post this on lsm mailing list.

The following trivial patch solves the problem.

Eric Dumazet 2832e9366a [PATCH] remove file.f_maxcount
struct file cleanup: f_maxcount has an unique value (INT_MAX).  Just use
the hard-wired value.

Robert Love 0eeca28300 [PATCH] inotify
inotify is intended to correct the deficiencies of dnotify, particularly
its inability to scale and its terrible user interface:

        * dnotify requires the opening of one fd per each directory
          that you intend to watch. This quickly results in too many
          open files and pins removable media, preventing unmount.
        * dnotify is directory-based. You only learn about changes to
          directories. Sure, a change to a file in a directory affects
          the directory, but you are then forced to keep a cache of
          stat structures.
        * dnotify's interface to user-space is awful.  Signals?

inotify provides a more usable, simple, powerful solution to file change
notification:

        * inotify's interface is a system call that returns a fd, not SIGIO.
	  You get a single fd, which is select()-able.
        * inotify has an event that says "the filesystem that the item
          you were watching is on was unmounted."
        * inotify can watch directories or files.

Inotify is currently used by Beagle (a desktop search infrastructure),
Gamin (a FAM replacement), and other projects.

Benjamin LaHaise 63e6880918 [PATCH] aio: fix do_sync_(read|write) to properly handle aio retries
When do_sync_(read|write) encounters an aio method that makes use of the
retry mechanism, they fail to correctly retry the operation.  This fixes
that by adding the appropriate sleep and retry mechanism.

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!
