Sure, it's perfectly fine to make those suggestions and discuss but the counter points have already been discussed (e.g. PSI is a known acronym associated with pressure and internal symbols all use them for brevity and uniqueness). There's no clear technically winning choice here and it's a decision of a relatively low importance given that it's confined to kernel config. I can't see any merit in turning it into a last-word match. Thanks. -- tejun
