Subject: Linux 3.11-rc4

It's that time of the week again..

"You apply 339 patches, what do you get
Another week older and deeper in debt
Saint Peter don't you call me 'cause I can't go
I owe my soul to the company store"

I had hoped things would start calming down, but rc4 is pretty much
exactly the same size as rc3 was. That said, the patches seem a bit
more spread out, and less interesting - which is a good thing. Boring
is good. Let's keep it that way, and try to make for fewer patches for
-rc5, ok? Because we are past half-way now, and I really want to see
just fixes.

We've got some arch updates (arm, parisc), but most of this is drivers
(mostly networking, usb and some drm updates). There's also some core
networking changes. And the printk code movement looks big if you
don't do git renames (ie like the patches I upload).

Subject: O_TMPFILE fs corruption (Re: Linux 3.11-rc4)

I still get filesystem corruption with O_TMPFILE. The program below,
run as flinktest foo proc (or flinktest foo linkat if you're root) will
produce a bogus inode. On ext4, once the inode is gone from cache, the
inode will be impossible to delete and will require a fsck to fix

A patch (not necessarily the appropriate fix) is here:
