Module symbol name mangling, __wake_up vs. __wake_up_sync

[Harbold, John]

Good Morning,

	I am making a Linux kernel with three module.  At the end of the
make process, depmod shows an error:

----------------------------------------------------------------------------
---------------------------

  Unresolved symbol in /lib/modules/linux-2.4.2_hhl20/kernel/driver/... .o

     __wake_up_sync

----------------------------------------------------------------------------
---------------------------

	Upon further investigation of the offending module, I found the
symbol, __wake_up, was successfully mangled, but not, __wake_up_sync.

	What is going on here.  The other two modules don't have this
problem.  What is the "magic" needed to solve this problem.

TIA

	John E. Harbold
