-Subject: RDMA/efa: Use ib_umem_num_dma_pages()
-
-From: Jason Gunthorpe <jgg@nvidia.com>
-
-[ Upstream commit 1f9b6827c85f9d9786f31a1434a16c917aae23b2 ]
-
-If ib_umem_find_best_pgsz() returns > PAGE_SIZE then the equation here is
-not correct. 'start' should be 'virt'. Change it to use the core code for
-page_num and the canonical calculation of page_shift.
-
-Fixes: 40ddb3f02083 ("RDMA/efa: Use API to get contiguous memory blocks aligned to device supported page size")
