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

Pull RDMA updates from Jason Gunthorpe:
 "About the normal size, still a lot of AI bug fixes and so on, but some
  interesting new functionality too:

   - Assorted locking, bounds-checking, cleanup, and error-path fixes
     across UCMA/CMA, bng_re, bnxt_re, cxgb4, EFA, ERDMA, HFI1, HNS,
     ionic, iRDMA, mlx4/mlx5, RXE, SIW, SRP/SRPT, and iSER target.

   - netlink report for max # of supported resources

   - get_zeroed_page()/etc removal

   - Robust udata for ionic

   - Allow unique RDMA device names per network namespace

   - Completion counters and v2 admit queue support for EFA

   - UC QP support for MANA

   - Completion timestamps for ionic

   - Harden uverbs data validation and resource lifetime handling,
     fixing several core use-after-free conditions.

   - bnxt_re toggle-page ownership and lifetime bug fixes

   - dmabuf SRQ support for mlx5"
