Hi! After 1 year of development, with the last 6-7 months spent polishing the API and testing the implementation, I think it is getting about time to release the RCU lock-free hash table in a new Userspace RCU version (0.7).
I recently described the guarantees provided by the hash table in more detail, and created tests for the uniqueness guarantee for traversals performed concurrently with add_unique and add_replace operations. I also added test modes that create long hash chains, to test corner-cases of the hash table. One small thing I wonder is whether we should document that the hash table update operations imply full memory barriers ? I'm personally getting confident that the hash table API is clean enough, and the implementation well tested, but I'd like to have your thoughts on the readiness of the hash table for production use.
