    afs: Skip bulkstat if stat cache looks full
    Currently, afs_lookup() will try to prefetch dir entries for normal
    dirs via bulkstat whenever multiple pids are reading that dir.
    However, if we already have a lot of vcaches, ShakeLooseVCaches may be
    struggling to limit the vcaches we already have. Entering
    afs_DoBulkStat can make this worse, since we grab afs_xvcache
    repeatedly, we may kick out other vcaches, and we'll possibly create
    30 new vcaches that may not even be used before they're evicted.
    To try to avoid this, skip running afs_DoBulkStat if it looks like the
    stat cache is really full.
