From a5be35632cf3048d3922e2e2fb05a4c6f0889ff0 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Thu, 5 Nov 2015 18:50:37 -0800 Subject: [PATCH] Documentation/filesystems/proc.txt: a little tidying There's an odd line about "Locked" at the head of the description of /proc/meminfo: it seems to have strayed from /proc/PID/smaps, so lead it back there. Move "Swap" and "SwapPss" descriptions down above it, to match the order in the file (though "PageSize"s still undescribed). The example of "Locked: 374 kB" (the same as Pss, neither Rss nor Size) is so unlikely as to be misleading: just make it 0, this is /bin/bash text; which would be "dw" (disabled write) not "de" (do not expand).
