An entry into the hash table.
To change overflow_next you need to hold the bin lock. To change the lru items you need to hold the hashtable lock. This structure is designed as part of key struct. And key pointer helps to get the surrounding structure. Data should be allocated on its own.
| lock_rw_type lruhash_entry::lock |
rwlock for access to the contents of the entry Note that it does not cover the lru_ and overflow_ ptrs.
Even with a writelock, you cannot change hash and key. You need to delete it to change hash or key.
