From 7d6c4dfa4de96d11b9d6adaf5aa5ca8c54670258 Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Wed, 15 Nov 2017 17:35:30 -0800 Subject: [PATCH] kmemleak: change /sys/kernel/debug/kmemleak permissions from 0444 to 0644 Kmemleak can be tweaked at runtime by writing commands into debugfs file. Root can use it anyway, but without the write-bit this interface isn't obvious.
