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
