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.)
