HPE Adapt (3 of at least 4) - Avoid page fault deadlock, stemming from copy-on-write race.

[andyw-lala]

HPE is planning to work with the community to enhance this xpmem repo, to provide the functionality currently supported by our in-house COS-only version. This issue is number 3 in a series of at least 4, and seeks to identify the known issues that must be addressed.

HPE xpmem currently relies on kernel mods (outside the xpmem kernel module) to avoid a known page fault deadlock, caused by a copy-on-write race condition. More details to follow.
