Call vos_pool_create and vos_pool_open in new deep-stack ULTs on the xstream to avoid pmemobj_create and pmemobj_open from potentially overflowing caller stacks.

Steps for the author:

  • Commit message follows the guidelines.
  • Appropriate Features or Test-tag pragmas were used.
  • Appropriate Functional Test Stages were run.
  • At least two positive code reviews including at least one code owner from each category referenced in the PR.
  • Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

  • Gatekeeper requested (daos-gatekeeper added as a reviewer).

Unclean cherry-pick due to master-release/2.6 differences in vos_pool_create parameters and of course copyright strings.
