[git pull] fuse: support splice() on fuse device

[Miklos Szeredi]

Linus,

This series adds support for splice() on the fuse device, allowing
userspace filesystem implementations to transfer data to/from the
kernel with reduced number of memory copies.

The only changes outside the fuse tree are addition of EXPORT_SYMBOLs.

Please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git for-linus

Thanks,
Miklos
