Subject: [PATCH] FUSE/CUSE: implement direct mmap support

Implement FUSE direct mmap support. The server can redirect client mmap
requests to any SHMLBA aligned offset in the custom address space attached
to the fuse channel. The address space is managed by the server using
mmap/munmap(2). The SHMLBA alignment requirement is necessary to avoid
cache aliasing issues on archs with virtually indexed caches as FUSE
direct mmaps are basically shared memory between clients and the server
