[GIT PULL] XArray for 5.5

[GIT PULL] XArray for 5.5

[Matthew Wilcox]

I had an oops live on stage at linux.conf.au this year, and it turned out
to be a bug in xas_find() which I can't prove isn't triggerable in the
current codebase.  Then in looking for the bug, I spotted two more bugs.
The bots have had a few days to chew on this with no problems reported,
and it passes the test-suite (which now has more tests to make sure
these problems don't come back).

So I feel pretty comfortable asking you to pull this, even though it's
so late in the development cycle.

The following changes since commit 0058b0a506e40d9a2c62015fe92eb64a44d78cd9:

Augh. I hate the timing, but looking through the changes I don't see
anything that makes me too worried apart from just how core and subtle
this is.

So pulled. This may be part of "we'll do an rc8 after all", but I'll
see. I was hoping to avoid that just because I have travel coming up,
and travel during the first week of the merge window is suboptimal for
me.

Oh well. These things happen,
