Detailed Description
Simple rpc item cache.
Highlights
- cache is protected with external lock m0_rpc_item_cache::ric_lock. It should be taken before calling any m0_rpc_item_cache function;
- cache assumes that same items have exactly the same xid;
- item xid uniqueness is responsibility of the user;
- cache protects items contained in from preliminary finalisation using rpc item reference counting (m0_rpc_item_get() and m0_rpc_item_put());
- m0_rpc_item_cache_lookup() doesn't take any reference. If user wants to use rpc item after deadline then reference should be taken by the user;
- rpc items are added to cache using m0_rpc_item_cache_add();
- rpc items are removed from the cache if:
- user calls m0_rpc_item_cache_del();
- user calls m0_rpc_item_cache_purge() - in this case all items with deadline passed are removed;
- deadline passed. Note: rpc items may remain in cache even after deadline.
