Log Message:
Change the way how puffs_fuse_node_create() behaves.
In puffs "create" and "open" are two separate operations with
atomicity achieved by locking the parent vnode. In fuse, on the other
hand, "create" is actually a create-and-open-atomically and the open
flags (O_RDWR, O_APPEND, ...) are passed via fi.flags. So the only way
to emulate the fuse semantics is to open the file with dummy flags and
then immediately close it.
You might think that we could simply use fuse->op.mknod all the time
but no, that's not possible because most file systems nowadays expect
op.mknod to be called only for non-regular files and many don't even
support it.
