Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

Pull rdma fixes from Jason Gunthorpe:
 "Nothing very exciting here, it has been a quiet cycle overall. Usual
  collection of small bug fixes:

   - irdma issues with CQ entries, VLAN completions and a mutex deadlock

   - Incorrect DCT packets in mlx5

   - Userspace triggered overflows in qib

   - Locking error in hfi

   - Typo in errno value in qib/hfi1

   - Double free in qedr

   - Leak of random kernel memory to userspace with a netlink callback"
