Yes the current code appears to be a mess of the word pid.

Because the suggestions I have seen are based on a partial understanding
of struct pid, and the suggested renames will reinforce misunderstandings
of what struct pid is.

I think having a core data structure named in a way that suggests it is
less then it is and reinforces peoples misconceptions is likely to be
more of a problem for maintenance than having your eyes glaze over
with seeing pid pid pid pid pid pid pid.

Further if we can't find a better name a rename is simply useless noise.

Please let's address the of peoples eyes glazing over but not by renaming
struct pid.  But by renaming the other sructures, variables of field names
that surround it.  Especially in kernel/pid.c where anything that is local
doesn't need a global prefix.
