SubjectOdd meminfo 2.4.14
Date
On 2.4.14 (upgraded from 2.4.10) first time I've seen this (I run vmstat all
the time).

I've got this exact same kernel on two other machines and they don't show
the funky cache #'s (yet).

I see in proc_misc.c that cache is printed with B(pg_size) in the first line
whereas it's printed with K(pg_size - swapper_space.nrpages) on the
"Cached:" line.
Both of them are wrong so it looks like pg_size is hosed somehow.

Also...pg_size is:
pg_size = atomic_read(&page_cache_size) - i.bufferram ;

What does pg_size have to do with bufferram????
