[$] The intersection of lazy RCU and memory reclaim

Joel Fernandes introduced himself to the memory-management track at the2023 Linux Storage, Filesystem,Memory-Management and BPF Summit as a co-maintainer of theread-copy-update (RCU) subsystem and an implementer of the "lazy RCU"functionality. Lazy RCU can improve performance, especially on systemsthat are not heavily utilized, but it also has some implications for memorymanagement that he wanted to discuss with the group.
