We'd like to invite MM developers to attend and will announce the topic for the next instance on the Monday prior to the next meeting. Our next Linux MM Alignment Session is scheduled for Wednesday. The details: Wednesday, September 23 * 9:00 - 10:00am PDT (UTC-7) https://meet.google.com/csb-wcds-xya backup: https://tel.meet/csb-wcds-xya?pin=1301132214803 doc: https://docs.google.com/document/d/1QQfZFPHa-pGEGf4A06cSqS0jdJwuZ8ro9JU5H0YSUQ0/view This week's topic will be Hwpoison, see the discussion in https://marc.info/?l=linux-kernel&m=178796007385067&w=2 No specific agenda other than to gather core MM developers with hwpoison developers and discuss: - where validation should live, esp with regard to the page allocator, or strict invariants in the page allocator + implications for the fastpath - handling for folios of arbitary orders - handling partial folio poisoning and split failures - race conditions between memory_failure() and concurrent alloc/free/compaction - soft offline for pages in the pcp lists We might even want to be bold and discuss a holistic design overhaul if it's warranted. If anybody has ideas for future topics, please let me know and I'll try to organize them. We'd love to have volunteers to lead future topics as well as requests for MM topics to be presented. Looking forward to seeing all of you on Wednesday!
