Readers can copy from hot page cache folios under RCU without taking a folio reference count, while page freeing defers memory recycling until an RCU grace period completes. This touches core MM logic (page allocator free paths, slowpath reclaim retry, memory failure, and page cache read paths in filemap and shmem) which is reachable through standard user-space file reading operations on 64-bit systems.)
