On SMP, I would have thought that only sharing the fd table while cloning tasks (CLONE_FILES) affects performance by bouncing the rwlock cache line. Are there a lot of common workloads where this happens ?
Anyway the files_struct_rcu patch for 2.5.38 is up at http://sourceforge.net/project/showfiles.php?group_id=8875&release_id=112473
