Hi Jakub,

Like we talked, I created new shared branch for this patch:
https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/log/?h=mana-shared

Because it took time, the base of this branch is v6.10-rc3 as I'm eager
to get the commit c9d52fb313d3 ("PCI: Revert the cfg_access_lock lockdep mechanism")
from Linus's master, and this shared patch gives me the reason to pull
the fix.

I see that your net-next didn't get -rc3 tag yet, so please pull it after you
advance net-next. After that I'll do the same in RDMA tree.

Thanks
