Hi all,
Today's linux-next merge of the security tree got a conflict in:
security/security.c
between commits:
1b67772e4e3f ("bpf,lsm: Refactor bpf_prog_alloc/bpf_prog_free LSM hooks")
a2431c7eabcf ("bpf,lsm: Refactor bpf_map_alloc/bpf_map_free LSM hooks")
f568a3d49af9 ("bpf,lsm: Add BPF token LSM hooks")
from the net-next tree and commit:
260017f31a8c ("lsm: use default hook return value in call_int_hook()")
from the security 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.

Stephen Rothwell
