VFS-SHWRSPL-ENH is an optional product bundle. It contains the product VfsShwrsplEnh, revision B.11.31.01. This product uses the new lock interfaces from SyncShwrspl product delivered in KERN-SHWRSPL, revision B.11.31.01 bundle, to enhance the pathname traversal component of HP-UX kernel to reduce vnode spinlock contention on high end superdomes.
