Subject: [PATCH rdma-next 0/6] Use ib_umem_find_best_pgsz() for all umems
Date: Mon, 26 Oct 2020 15:26:29 +0200
Message-ID: <20201026132635.1337663-1-leon@kernel.org> (raw)

From: Leon Romanovsky <leonro@nvidia.com>

From Jason:

Move the remaining cases working with umems to use versions of
ib_umem_find_best_pgsz() tailored to the calculations the devices
requires.

Unlike a MR there is no IOVA, instead a page offset from the starting page
is possible, with various restrictions.

Compute the best page size to meet the page_offset restrictions.

Thanks
