[$] The interaction between memory reclaim and RCU

The 2024 LinuxStorage, Filesystem, Memory-Management and BPF Summit was a developmentconference, where discussion was prioritized and presentations with a lotof slides were discouraged. Paul McKenney seemingly flouted thisconvention in a joint session of the storage, filesystem, andmemory-management tracks where he presented about 50slides - in fiveminutes, twice. The subject was the use of the read-copy-update (RCU)mechanism in the memory-reclaim process, and whether changes to RCU wouldbe needed for that purpose.
