Subject: [git pull] fuse: add store and retrieve support

Linus,

Please pull

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

This series enables userspace filesystems to store and retrieve data
in the kernel page cache.  This allows filesystems to

 - poll for changes on mmap regions
 - update contents of mmaped or cached regions
 - pre-fill cache

This interface is also necessary to support mmap on character devices
(CUSE), which in turn is necessary for full OSS emulation (Tejun's
OSSProxy project).  Mmap support is not yet finished but coming
shortly.

Thanks,
Miklos
