Actually, my patch makes no attempt to change the actual format
of /proc/meminfo; it changes only what is necessary to handle RAM or
swap larger than 4GB by using ULLs instead of ULs.
As for modernizing/fixing the format, true, the Mem: and Swap: lines do
not exist in modern Linux, nor does the MemShared: line. I would like
to actually define at least HighTotal and HighFree; I'll try to look
into that further soon. As for the rest of Linux's /proc/meminfo, I'll
have to see how many other lines can be reasonably determined (if they
would exist at all) on Windows.
So with the ULL changes, if I remove the Mem, Swap, and MemShared lines,
will that do for now?
