    linprocfs(4): Fixup process size in the /proc/pid/stat file
    
    According to the Linux sources the kernel exposes a proces virtual
    memory size via proc filesystem into the three files - stat, status
    and statm. This is the struct mm->total_vm value adjusted to the
    corresponding units - bytes, kilobytes and pages.
    
    The fix is based on a fernape@ analysis.
