[PATCH rdma-next 0/6] Use ib_umem_find_best_pgsz() for all umems

[Leon Romanovsky]

From: Leon Romanovsky <leonro@xxxxxxxxxx>

>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
