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.
