    fs: dcache rationalise dget variants · dc0474be

    dget_locked was a shortcut to avoid the lazy lru manipulation when we already
    held dcache_lock (lru manipulation was relatively cheap at that point).
    However, how that the lru lock is an innermost one, we never hold it at any
    caller, so the lock cost can now be avoided. We already have well working lazy
    dcache LRU, so it should be fine to defer LRU manipulations to scan time.
