I look my system and others:
1) SUSE SP2: 3.0.13-0.27-default (uname -a); test PASS; -r--r--r-- 1 root root 0 Oct 30 16:13 /proc/self/pagemap
2) Ubuntu: 3.13.0-32-generic; test PASS; -r--r--r--. 1 cuibixuan cuibixuan 0 10? 30 16:19 /proc/self/pagemap
3) SUSE: 4.2.0-0.11-default; test FAIL; -r-------- 1 root root 0 Nov 13 01:39 /proc/self/pagemap
4) arm64: linux 4.1.6; test FAIL; -r-------- 1 root root 0 Jan 18 01:53 /proc/self/pagemap
Maybe the higher version of the kernel change the file attributes
of /proc/self/pagemap, I think.
But I read the Documentation/vm/pagemap.txt and look at the source code in kernel,
can't get it. :-(
Someone help?
