Alexander Motin 1fcdb58634 Do not ignore arc_adjust() return value. ... This covers scenario when ARC may not shrink as fast as it could: 1. arc_size < arc_c and arc_adjust() does not evict anything, returning zero to arc_reclaim_thread(); 2. arc_available_memory() reports memory pressure, which can not be satisfied by arc_kmem_reap_now(); 3. arc_shrink() reduces arc_c and calls arc_adjust(), return of which is ignored; 4. even if the last arc_adjust() could not satisfy arc_size < arc_c, arc_reclaim_thread() will still go to sleep, since the first one returned zero.
