The "- v2" suffix is a patch-revision marker that must be stripped from
the final commit subject before merging.

The subject should also follow the LTP convention of naming the
subsystem and what is being added, for example:

  hugetlb/hugemmap: add hugemmap33 to test hugetlbfs quota accounting

Ground Rule 4 requires that when a test sets .needs_root = 1, the
reason must be stated in the doc comment.  The test mounts a second
hugetlbfs instance with a quota limit in setup(), which requires
CAP_SYS_ADMIN, but the description block is silent on this.

A sentence like the following should be added:

  Root is required to mount the quota-limited hugetlbfs instance.

Verdict - Needs revision
