Hi all,
Today's linux-next merge of the bpf-next tree got a conflict in:
drivers/net/ethernet/intel/ice/ice_xsk.c
between commit:
675f176b4dcc ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net")
from the net-next tree and commit:
aa1d3faf71a6 ("ice: Robustify cleaning/completing XDP Tx buffers")
from the bpf-next tree.
I fixed it up (I guessed - 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.
