I don't disagree that naming is important, I would only add,
non-sarcastically, that naming is hard (as a coworker likes to remind
me on a regular basis).

My personal take on the "secure" function variant is that it provides
some indication that this is tied to a LSM hook. For better or worse,
all of the LSM hooks start off with "security_" and most (all?) of the
LSM blob void pointers in various structs throughout the kernel are
named "security". While arguments can be made about the merits of
that depending on how you define "security", the fact remains that
they are named that way. If you, or anyone else reading this, has
another suggestion for the function names I'm listening ...
