Because it would be silly to write another file system just for that rather obscure feature, would it be possible to use a subdirectory in your new shm filesystem? I haven't looked at the code at all yet, and don't know if it can even deal with directories and special devices. Do you have objections to such a direction? -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
