Abstract
A computer program product, system, and computer implemented method for fast reuse of locking data structures prior movement of entries to a cache free list. The approach disclosed herein enables management of lock management structures. Specifically, the approaches provided herein are directed towards use of lock management structures where items are managed using at least a recycle list. A recycle list and a resource list pair associated with the recycle list are controlled using a single latch, where there are any number of buckets that each include a recycle list and a resource list pair. In addition, in some embodiments, a free list is also maintained, whereas resource lists and recycle lists have a one-to-one relationship with each other, the free list has a one-to-many relationship with the buckets and lists therein.
