Details

[wlemkows]

This bug relates to the async functionality, which in release 1.13 is marked as deprecated https://github.com/pmem/pmdk/pull/5552. In this regard, it is not a critical issue.

[janekmi]

Note: It is related to libminiasync which is experimental.

[janekmi]

The asynchronous libpmem2 API has been scrapped. No fixes for this experimental library to the historical releases are expected.
