Hi Greg,
Below are few build errors in libbpf code:
Here are few libbpf commits:
David Vernet <void@xxxxxxxxxxxxx>
libbpf: Don't take direct pointers into BTF data from st_ops
Eduard Zingerman <eddyz87@xxxxxxxxx>
libbpf: Sync progs autoload with maps autocreate for struct_ops maps
Kui-Feng Lee <thinker.li@xxxxxxxxx>
libbpf: Convert st_ops->data to shadow type.
Kui-Feng Lee <thinker.li@xxxxxxxxx>
libbpf: Find correct module BTFs for struct_ops maps and progs.
Andrii Nakryiko <andrii@xxxxxxxxxx>
libbpf: use stable map placeholder FDs
+ make -s ARCH=x86 KBUILD_SYMTYPES=y -j32 bzImage modules

^~~~~~~~~~~~~~~~~~~~~~
libbpf.c:5215:50: note: each undeclared identifier is reported only once
for each function it appears in
Looks like we have more than one compilation error in libbpf code.
Thanks,
