I think we should have some sufficient commentary in the code that describes why we do this. > +static inline bool compact_check_resched(struct compact_control *cc) > +{ I'm not sure that compact_check_resched() is the appropriate name. Sure, it specifies what the current implementation is, but what it's really actually doing is determining when compaction should abort prematurely. Something like compact_should_abort()? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
