Subject[PATCH 1/4] mm, documentation: clarify /proc/pid/status VmSwap limitations
Date
The documentation for /proc/pid/status does not mention that the value of
VmSwap counts only swapped out anonymous private pages and not shmem. This is
not obvious, so document this limitation.

I've noticed that proc(5) manpage is currently missing the VmSwap field
altogether.
