Re: [fuse-devel] O_CREAT in open()?

The way O_CREAT works in linux, is that if the file doesn't exist the
VFS calls the create() method, and then calls the open() method.  Open
will never actually have to create the file, so it doesn't need
O_CREAT.

Why do you get empty files?

Nothing especially bad would happen.  Though I'm still curious why you
need O_CREAT at open() time.
