Subject: [PATCH rdma-next 08/14] RDMA/core: Do not erase the type of ib_srq.uobject
Date: Wed,  8 Jan 2020 19:22:00 +0200
Message-ID: <1578504126-9400-9-git-send-email-yishaih@mellanox.com> (raw)
In-Reply-To: <1578504126-9400-1-git-send-email-yishaih@mellanox.com>

From: Jason Gunthorpe <jgg@mellanox.com>

This is a struct ib_usrq_object pointer, instead of using container_of()
all over the place just store it with its actual type.
