Subject: [PATCH rdma-next 1/2] RDMA/core: Remove unused ib_resize_cq() implementation
Date: Wed, 18 Mar 2026 12:02:36 +0200	[thread overview]
Message-ID: <20260318-resize_cq-type-v1-1-b2846ed18846@nvidia.com> (raw)
In-Reply-To: <20260318-resize_cq-type-v1-0-b2846ed18846@nvidia.com>

From: Leon Romanovsky <leonro@nvidia.com>

There are no in-kernel users of the CQ resize functionality, so drop it.
