Re: [PATCH][5/8] proc: export mlocked pages info through "/proc/meminfo: Wired"

[Stone Wang]

The name "Wired" could be changed to which one most kids think better
fits the job.

I choosed "Wired" for:
"Locked" will conflict with PG_locked bit of a pags.
"Pinned" indicates a short-term lock,so not fits the job too.
