Subject: [PATCHSET 2/5] fuse2fs: prepare for kernel driver replacement

Hi all,

This series creates a new "kernel" mount option that signals to the
fuse2fs driver that it's being used as a containerizable replacement
for the kernel driver.  This has the effect of delegating quite a
lot of decisionmaking to the kernel, and opening access to users
other than whoever's running the fuse2fs server.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

Comments and questions are, as always, welcome.

 * fuse2fs: add dummy acl/user_xattr mount options
 * fuse2fs: set fuse subtype via argv[0] if possible
 * fuse2fs: make "ro" behavior consistent with the kernel
