I roughly read [BZ #12416] and I found comment#3 says it's a kernel
bug. But I'm not exactly sure what he said. Can anyone please explain
which fault do kernel has? If you guys don't want kernel change at
all, please ignore me.

comment#1 claimed that it was a kernel bug that changing permissions causes a vma split. But that was a misunderstanding of the kernel. I don't think any aspect of this issue warrants considering any kernel changes.

Thank you, Roland! I'm relieved to hear that.
