The value of mr->ndescs greater than mr->max_descs is set in the function mlx5_ib_sg_to_klms() if sg_nents is greater than mr->max_descs. This is an invalid value and it causes the following error when registering mr: mlx5_0:dump_cqe:276:(pid 193): dump error cqe 00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00000030: 00 00 00 00 0f 00 78 06 25 00 00 8b 08 1e 8f d3 Cc: <stable@vger.kernel.org> # 4.5 Fixes: b005d316 ("mlx5: Add arbitrary sg list support") Signed-off-by:
