Hi Hugh and others, In 2007, there were some discussions on whether to allow opens to specify O_DIRECT for files backed by tmpfs.[1][2] On the surface, it sounds like a completely crazy thing to do. However, distributions like Fedora are now defaulting to using a tmpfs /tmp. I'm not aware of any applications that open temp files using O_DIRECT, but I wanted to get some new discussion going on whether this is a reasonable thing to expect to work. Thoughts?
