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.
