Re: [PATCH iproute2-next v3] rdma: display resource limits in curr/max format

[Tao Cui <cui.tao@linux.dev>]

Hi David,

Thanks for taking a look.

The kernel counterpart that introduces this uapi attribute is the
following patch, currently under review on the rdma list and not yet in
Linus' tree:

  [PATCH rdma-next v3] RDMA/nldev: add resource summary max values for usage display
  https://lore.kernel.org/all/20260615003646.168704-1-cui.tao@linux.dev/

That is the one adding RDMA_NLDEV_ATTR_RES_SUMMARY_ENTRY_MAX.

You're right that the iproute2 side should reference the kernel patch.
I'll add a Link to it in the commit log of the next revision, e.g.:

  Link: https://lore.kernel.org/all/20260615003646.168704-1-cui.tao@linux.dev/

If you'd prefer, I can also hold this iproute2 patch until the kernel
side has landed, so the uapi is already in tree when it goes in. Happy
to do whichever you think is best.

Thanks,
Tao
