Huge pages can increase the performance of many programs, but they can also have unfortunate performance impacts of their own. Over the last few years, multi-size transparent huge pages (mTHPs) have increasingly been seen as a happy medium that bring the benefits of huge pages at a lower cost. The system cannot benefit from mTHPs, though, if it does not create them; two developers have independently posted patches to enable the creation of mTHPs in the background.

Extreme right forces actively target members of our communities and discriminate based on ethnicity and gender, political background, sexual orientation, disabilities, nationality and faith. However diversity is an important asset in free/libre software communities and it is what makes our software great and development productive.

By targeting some of our most active translators, nicest designers, best developers and all other motivated contributors, they are hurting the free/libre software ecosystem as a whole.
