What rules exactly? I don't think any of those functions are declared
with __must_check
Coding style should never get in the way of what is right.
The classic way to explicitely discard a return value is a cast to void,
but that is generally considered
ugly in the Linux kernel.
One could possibly add a comment about this at least.
