Subject: [PATCH] kmemleak: change /sys/kernel/debug/kmemleak permissions from 0444 to 0644
Date: Fri, 06 Oct 2017 14:39:25 +0300 [thread overview]
Message-ID: <150728996582.744328.11541332857988399411.stgit@buzz> (raw)
Kmemleak could be tweaked in runtime by writing commands into debugfs file.
Root anyway can use it, but without write-bit this interface isn't obvious.
