It replaces a blocking folio_lock after dropping the page table lock with a folio_trylock under the page table lock. This code path is directly reachable from unprivileged userspace via the madvise and process_madvise system calls on THP mappings, warranting fuzzing to ensure proper synchronization and behavior under race conditions.)
