From 8f5abe842e84ba9e72485ddd9dc02a3562b54e2a Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 27 Nov 2017 16:45:56 -0800 Subject: proc: don't report kernel addresses in /proc//stack This just changes the file to report them as zero, although maybe even that could be removed. I checked, and at least procps doesn't actually seem to parse the 'stack' file at all. And since the file doesn't necessarily even exist (it requires CONFIG_STACKTRACE), possibly other tools don't really use it either. That said, in case somebody parses it with tools, just having that zero there should keep such tools happy.
