When using linked list we have to open code the locking, search, and destroy operations with the loops even if data structure doesn't fall into the fast path. One of the main advantage of having XArray to store, search, and remove items is that it handles all the locking by itself, avoids the loops when using linked lists, provides clear API to replace the linked list's search and destroy loops. This patch replaces the ctrl->cel list with XArray and removes :- a. Extra code needed for the linked list for ctrl->cel item management such as nvme_find_cel(). b. Destroy loop in the nvme_free_ctrl(). c. Explicit insertion locking in the nvme_get_effects_log().
