[GIT PULL] xen: tmem: self-ballooning and frontswap-selfshriking

[Dan Magenheimer]

Hi Konrad --

Please pull the following branch into your Xen for-linus tree
for the upcoming 3.1 window.

git://git.kernel.org/pub/scm/linux/kernel/git/djm/tmem.git #xen-tmem-selfballoon-v3

The branch is based off of 3.0-rc1.

This single commit introduces two in-kernel drivers for Xen
transcendent memory ("tmem") that complement cleancache and
frontswap.  Both use control theory to dynamically adjust and
optimize memory utilization.  Much more detail is in the
header comment of the file.

      xen: tmem: self-ballooning and frontswap self-shrinking

Note that this patch has a slight build dependency on last week's:

afec6e04922d0c8c7e244be2e544bac5e7e36294 xen: prepare tmem shim to handle frontswap

in your devel/next-3.0 branch (because tmem_enabled is EXPORT_SYM'ed
in that commit and extern'ed in a file in this commit).  I don't
think this is a problem as you've already pushed that commit
to linux-next, but am noting the dependency in case some kind
of commit reordering were to occur.

Thanks,
Dan
