From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx> Hi, This is an alternative series from "[PATCH 0/5] Use memfd if possible". Instead of automatically using memfd for anonymous memory when available (as suggested by Daniel), it introduces the "memfd" memory backing type. Although using memfd transparently when possible is a good idea, it is a source of various complications for migration & save/restore. This could eventually be challenged in a different series. The first two patches have been modified and reviewed by John Ferlan. Hopefully they can be merged early, regardless of the last patch outcome, to avoid the painful rebase conflicts due to capabilities checks introduction.
