Subject: Re: [PATCH v2] hugetlbfs: skip VMAs without shareable locks in hugetlb_vmdelete_list

Hi Mark,

Thank you for the report and bisection. I see the hugetlbfs-madvise 
test is failing with unexpected free huge pages count.

I'm investigating why the VMAs skipped in my patch aren't getting 
their pages freed properly. I'll analyze the test code and work on 
a fix.

I'll follow up once I understand the root cause.

Deepanshu
