Hi all, After merging the bpf-next tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: ld: warning: discarding dynamic section .glink ld: warning: discarding dynamic section .plt ld: linkage table error against `bpf_trampoline_unlink_cgroup_shim' ld: stubs don't match calculated size ld: can not build stubs: bad value ld: kernel/bpf/cgroup.o: in function `.bpf_cgroup_link_release.part.0': cgroup.c:(.text+0x2fc4): undefined reference to `.bpf_trampoline_unlink_cgroup_shim' ld: kernel/bpf/cgroup.o: in function `.cgroup_bpf_release': cgroup.c:(.text+0x33b0): undefined reference to `.bpf_trampoline_unlink_cgroup_shim' ld: cgroup.c:(.text+0x33c0): undefined reference to `.bpf_trampoline_unlink_cgroup_shim' Caused by commit 3908fcddc65d ("bpf: fix lsm_cgroup build errors on esoteric configs") I have reverted that commit for today. -- Cheers, Stephen Rothwell
