Ahh okay. cscope will do that too.... But all have __exit.
The trick is that one of them *shouldn't* have __exit. With cscope
you'll have to use the "Find functions calling this function:"
mode to try and find the __init function that is calling an
__exit function.
Urgh... Does it have to be that difficult?

Sometimes yes ... but in this case no.
I flipped config options on and off until I tracked the problem down
into the loopback driver, and then manually ran modpost on
drivers/block/built-in.o to reveal:
....Nothing.
Something is borken in modpost because I found a bug in the loopback
code which is a _REAL_ bug.
The -mm tree contains a patch which calls __exit loop_exit from __init
loop_init .
(I'll submit this patch directly to Andrew in about 5 mins. I'm
including the patch here just so Christoph can grab it and continue on.)
Christoph, this is one less beer I owe you :) :) :)
Tony, the ia64 section mismatch "whack-a-mole" is far from over :(
