kernel + sh: Another stream overhaul Certain streams can now be opened by name by prefixing the name with a colon (':'). The only supported named stream at the moment is :fb, which streams to/from the background framebuffer. A new syscall called `get_size` was also added, which should be used instead of `ryfs_get_size`. This new syscall supports getting the size of streams. 2023-03-31 07:16:31 +02:00			`call get_size`
