Yes, except I'm not sure it needs to be split, that depends on whether sending a request relies on any initialization in that function or not. > But we can’t return from fuse_fill_super() until that root node is set > up, can we? If so, we‘d need to await that FUSE_INIT reply in that > function. Can we do that? Sure, just need to send FUSE_INIT with fuse_simple_request() instead of fuse_simple_background(). Thanks, Miklos
