[PATCH rdma-next 00/12] RDMA fixes 2018-06-24

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

Hi,

This is bunch of patches trigged by running syzkaller internally.

I'm sending them based on rdma-next mainly for two reasons:
1, Most of the patches fix the old issues and it doesn't matter when
they will hit the Linus's tree: now or later in a couple of weeks
during merge window.
2. They interleave with code cleanup, mlx5-next patches and Michael's
feedback on flow counters series.

Thanks
