Why are LowTotal, LowFree, HighTotal, and HighFree missing from /proc/meminfo on x86_64 RHEL 6?

Solution Unverified - Updated -

Issue

  • The /proc/meminfo contents have changed. Releases prior to Red Hat Enterprise Linux (RHEL) 6 had the following information:
    • HighTotal and HighFree — The total and free amount of memory, in kilobytes, that is not directly mapped into kernel space. The HighTotal value can vary based on the type of kernel used.
    • LowTotal and LowFree — The total and free amount of memory, in kilobytes, that is directly mapped into kernel space. The LowTotal value can vary based on the type of kernel used.
  • There are values missing in /proc/meminfo in RHEL 6 that used to be there in prior releases.

Environment

  • Red Hat Enterprise Linux (RHEL) 5
  • Red Hat Enterprise Linux (RHEL) 6, 64 bit
