But I am *NOT* talking about coda! I am talking about it's backdoor to
kernel through which the userland CLIENT talks talks to kernel. And
that's basicaly just VFS operations exported to userspace using
structures sent down a char device (unices) or as messages (winNT).
Read/write/readdir is done using temporary files there, but we would
have cache, so that's ok with us. And all the other important operations
like rename, mkdir, rmdir, link, unlink etc. are sent as commands,
immediately, and they are serialized (because they go up a single
channel).
