Subject: Re: [PATCH] KERNEL: resource: Fix bug on leakage in /proc/iomem file
First, I wrote your attached patch, but then I thought zeroing other
/proc/iomem values would be better. So I changed it.
Most distros don't use KASLR, but they use kptr_restrict. Without KASLR,
kptr_restirct most likely useless. As you said these things should be
done long ago
