linux-next: manual merge of the tip tree with the net-next tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Today's linux-next merge of the tip tree got a conflict in:

  arch/x86/net/bpf_jit_comp.c

between commit:

  1022a5498f6f ("bpf, x86_64: Use bpf_jit_binary_pack_alloc")

from the net-next tree and commit:

  9e1db76f44de ("x86,bpf: Fix bpf_arch_text_poke()")

from the tip 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.
