These patches implement mmap support for CUSE (character device in userspace).

The immediate application for this is to get old games requiring OSS/mmap
support to work with OSS Proxy, written by Tejun.  So firstly this is a call for
testers; please try this out and report any problems.

Three pieces are needed:

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

fuse:
  git://fuse.git.sourceforge.net/gitroot/fuse/fuse master

osspd:
  git://fuse.git.sourceforge.net/gitroot/fuse/osspd master


Comments about the interface and implementation in general (not related to OSS
proxy) are very welcome as well.

Thanks,
Miklos
