Subject: [PATCHSET] CUSE: implement CUSE

This patchset implements CUSE - Character device in Userspace.  Except
for initialization sequence and creation of character device instead
of a mount, CUSE isn't very different from FUSE.

This patchset is consisted of the following five patches.

  0001-FUSE-add-fuse_-prefix-to-several-functions.patch
  0002-FUSE-export-symbols-to-be-used-by-CUSE.patch
  0003-FUSE-separate-out-fuse_conn_init-from-new_conn.patch
  0004-FUSE-add-fuse_conn-release.patch
  0005-CUSE-implement-CUSE-Character-device-in-Userspace.patch

0001-0004 prepares FUSE for CUSE addition and 0005 implements CUSE.
Corresponding libfuse changes will be posted separately.

This patchset is on top of...

  2.6.27-rc4 (b8e6c91c74e9f0279b7c51048779b3d62da60b88)
+ [1] 9p-use-single-poller patchset
+ [2] wait-kill-is_sync_wait
+ [3] poll-allow-f_op_poll-to-sleep
+ [4] uevent updates (2 patches)
+ [5] char_dev-add-release
+ [6] extend-FUSE patchset

The above three patches allow f_op->poll() to sleep and 0007 depends
on it.

This patchset is available in the following git tree.
