[Bug 1729510] Re: libhugetlbfs failed with "[Errno 95] Operation not supported" on s390x zVM

2018-09-12 Thread Po-Hsu Lin 
As 17.10 has reaches its EOL, and the test was blacklisted on Bionic and onward.
I will mark this task as Won't fix.

[Bug 1729510] Re: libhugetlbfs failed with "[Errno 95] Operation not supported" on s390x zVM

2017-11-02 Thread Po-Hsu Lin 
The system got HUGETLB enabled in the config:

$ cat /boot/config-4.13.0-16-generic  | grep HUGETLB
CONFIG_CGROUP_HUGETLB=y
CONFIG_HUGETLBFS=y
CONFIG_HUGETLB_PAGE=y

But there is no hugepage_size in meminfo:
$ cat /proc/meminfo  | grep Hugepagesize

Looks like hugepage is not supported. I will fix the detection part in
our test suite.

Not sure if this is an expected behaviour in the kernel.
