[GIT PULL] (xen) stable/blkfront for 2.6.40

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

Hey Jens,

Please pull:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/blkfront

which has changes since git commit 8e10cd74342c7f5ce259cceca36f6eba084f5d58
Linus Torvalds (1):
    Linux 2.6.39-rc5

The git commit includes a bug-fix, and a set of patches to allow the blkfront
driver to use 'feature-flush-cache' feature. The 'flush-cache' is basically
the equivalent of the new REQ_FLUSH command (the old 'feature-barrier' is
still present in the driver in case the backend supports that).

If you prefer for me to ask Linus to pull this git tree since it includes
a patch to the include/xen/interface/.. directory - I can do that as long as
you are OK with that.


Konrad Rzeszutek Wilk (2):
      xen-blkfront: Provide for 'feature-flush-cache' the BLKIF_OP_WRITE_FLUSH_CACHE operation.
      xen-blkfront: Introduce BLKIF_OP_FLUSH_DISKCACHE support.

Marek Marczykowski (1):
      xen-blkfront: fix data size for xenbus_gather in blkfront_connect
