>>> do_mounts.c:(.text+0x66): multiple definition of `locks_owner_has_blockers'; init/main.o:main.c:(.text+0x0): first defined here

I looked through all the functions listed as having multiple
definition of `locks_owner_has_blockers' such as init/main.o:main.c,
arch/x86/kernel/head32.c, init/do_mounts_rd.c and many others.
None of these functions has 'locks_owner_has_blockers' defined.
I think there is a problem with the tools that detects this
error, can you help to verify?

Thanks,
-Dai
