    [PATCH] knfsd: An assortment of little fixes to the sunrpc cache code · 4013edea
    NeilBrown 提交于
    - in cache_check, h must be non-NULL as it has been de-referenced,
      so don't bother checking for NULL.
    
    - When a cache-item is updated, we need to call cache_revisit_request to see
      if there is a pending request waiting for that item.  We were using
      a transition to CACHE_VALID to see if that was needed, however that is
      wrong as an expired entry will still be marked 'valid' (as the data is valid
      and will need to be released).  So instead use an off transition for
      CACHE_PENDING which is exactly the right thing to test.
    
    - Add a little bit more debugging info.
