Subject: linux-next: manual merge of the rdma tree with the origin tree
Date: Mon, 19 Jan 2026 16:25:58 +0000 [thread overview]
Message-ID: <aW5bFiqwjxpet-Tj@sirena.org.uk> (raw)
Hi all,
Today's linux-next merge of the rdma tree got a conflict in:
drivers/infiniband/hw/mana/cq.c
between commit:
887bfe5986396 ("RDMA/mana_ib: check cqe length for kernel CQs")
from the origin tree and commit:
f972bde7326e9 ("RDMA/mana_ib: Take CQ type from the device type")
from the rdma tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
