This file contains 64-bit masks corresponding to each physical page frame; it is indexed by page frame number (see the discussion of /proc/pid/pagemap). The bits are as follows:

For further details on the meanings of these bits, see the kernel source file Documentation/admin−guide/mm/pagemap.rst. Before Linux 2.6.29, KPF_WRITEBACK, KPF_RECLAIM, KPF_BUDDY, and KPF_LOCKED did not report correctly.

The /proc/kpageflags file is present only if the CONFIG_PROC_PAGE_MONITOR kernel configuration option is enabled.
