This is kind of a weird situation. We're caching locally the content of files aren't really regular files and probably shouldn't be cached. I'm not sure what the best way to deal with that is. I wonder if there's some way to detect that and mark then non-cacheable. (Assuming the server can be told not to even serve them). Can we detect that the EOF length doesn't match i_size and set a flag to say "don't cache" in netfs_inode::flags? David
