/proc/kpagecount - count of mappings of physical pages
- /proc/kpagecount (since Linux 2.6.25)
- This file contains a 64-bit count of the number of times each physical
page frame is mapped, indexed by page frame number (see the discussion of
/proc/pid/pagemap).
- The /proc/kpagecount file is present only if the
CONFIG_PROC_PAGE_MONITOR kernel configuration option is
enabled.
