Makefile and config are the same as uploaded here: #548

With a vanilla clang version 9.0.0 (363704) and Kernel 5.2-rc5 (Suse), I get the following objtool error:

fs/hfsplus/xattr.o: warning: objtool: hfsplus_create_attributes_file()+0x395: unreachable instruction

Not reproducible any longer with linux-next-next-20190726 and clang version 10.0.0 (366783).

probably was related to loop unrolling, which I fixed in #551.
