Driver work. The week's heaviest change lands snapshot promotion support in the Infinidat driver (~550 lines), letting operators promote a snapshot in place within the backend (940236). Dell PowerFlex gets a sizeable fix to how the image cache counts vTree size, correcting the accounting used when deciding whether cached images fit. Elsewhere in driver land, Everpure now reports its backend as an explicit single pool, NetApp ONTAP's REST client stops dropping an SSC extra spec during volume type matching, and Nexenta silences a re.split deprecation warning.

Maintenance. A dead only_quotas code path in quota_destroy_all_by_project is removed, trimming unused branching from the quota layer. Documentation drops the deprecated queue_if_no_path setting from the Nimble multipath example, and three small patches sweep up spelling mistakes across the tree.
