Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma fixes from Jason Gunthorpe:
"A mixture of small bug fixes and a small security issue:
- WARN_ON when IPoIB is automatically moved between namespaces
- Long standing bug where mlx5 would use the wrong page for the
doorbell recovery memory if fork is used
- Security fix for mlx4 that disables the timestamp feature
- Several crashers for mlx5
- Plug a recent mlx5 memory leak for the sig_mr"
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
IB/mlx5: Fix initializing CQ fragments buffer
RDMA/mlx5: Delete right entry from MR signature database
RDMA: Verify port when creating flow rule
RDMA/mlx5: Block FDB rules when not in switchdev mode
RDMA/mlx4: Do not map the core_clock page to user space unless enabled
RDMA/mlx5: Use different doorbell memory for different processes
RDMA/ipoib: Fix warning caused by destroying non-initial netns
