Hi all,
Today's linux-next merge of the net-next tree got a conflict in:
drivers/net/bonding/bond_main.c
between commits:
ed7d4f023b1a ("bonding: Rename slave_arr to usable_slaves")
c071d91d2a89 ("bonding: Add helper function to get the xmit slave based on hash")
29d5bbccb3a1 ("bonding: Add helper function to get the xmit slave in rr mode")
from the rdma and mlx5-next trees and commit:
ae46f184bc1f ("bonding: propagate transmit status")
from the net-next tree.
I fixed it up (I think - 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.
