## Message

```
std.os: Allow write functions to return INVAL errors

In Linux when interacting with the virtual file system when writing
in invalid value to a file the OS will return errno 22 (INVAL).

Instead of triggering an unreachable, this change now returns a
newly introduced error.InvalidArgument.
