- * just like a template in C++, this macro does cache lookup
- * for us.
- * The function is passed some sort of HANDLE from which a cache_detail
- * structure can be determined (via SETUP, DETAIL), a template
- * cache entry (type RTN*), and a "set" flag.  Using the HASHFN and the 
- * TEST, the function will try to find a matching cache entry in the cache.
- * If "set" == 0 :
- *    If an entry is found, it is returned
- *    If no entry is found, a new non-VALID entry is created.
- * If "set" == 1 and INPLACE == 0 :
- *    If no entry is found a new one is inserted with data from "template"
- *    If a non-CACHE_VALID entry is found, it is updated from template using UPDATE
- *    If a CACHE_VALID entry is found, a new entry is swapped in with data
- *       from "template"
- * If set == 1, and INPLACE == 1 :
- *    As above, except that if a CACHE_VALID entry is found, we UPDATE in place
- *       instead of swapping in a new entry.
- *
- * If the passed handle has the CACHE_NEGATIVE flag set, then UPDATE is not
- * run but insteead CACHE_NEGATIVE is set in any new item.
 
- *  In any case, the new entry is returned with a reference count.
- *
- *    
- * RTN is a struct type for a cache entry
- * MEMBER is the member of the cache which is cache_head, which must be first
- * FNAME is the name for the function   
- * ARGS are arguments to function and must contain RTN *item, int set.  May
- *   also contain something to be usedby SETUP or DETAIL to find cache_detail.
- * SETUP  locates the cache detail and makes it available as...
- * DETAIL identifies the cache detail, possibly set up by SETUP
- * HASHFN returns a hash value of the cache entry "item"
- * TEST  tests if "tmp" matches "item"
- * INIT copies key information from "item" to "new"
- * UPDATE copies content information from "item" to "tmp"
- * INPLACE is true if updates can happen inplace rather than allocating a new structure
- *
- * WARNING: any substantial changes to this must be reflected in
- *   net/sunrpc/svcauth.c(auth_domain_lookup)
- *  which is a similar routine that is open-coded.
