We would like to continue the discussion about code tagging use for memory allocation profiling. The code tagging framework [1] and its applications were posted as an RFC [2] and discussed at LPC 2022. It has many applications proposed in the RFC but we would like to focus on its application for memory profiling. It can be used as a low-overhead solution to track memory leaks, rank memory consumers by the amount of memory they use, identify memory allocation hot paths and possible other use cases. Kent Overstreet and I worked on simplifying the solution, minimizing the overhead and implementing features requested during RFC review. Kent Overstreet, Michal Hocko, Johannes Weiner, Matthew Wilcox, Andrew Morton, David Hildenbrand, Vlastimil Babka, Roman Gushchin would be good participants.
