While testing linux mainline v3.5, it comes out the following warning:

WARNING: drivers/scsi/fcoe/libfcoe.o(.init.text+0x21): Section mismatch in reference from the function
init_module() to the function .exit.text:fcoe_transport_exit()
The function __init init_module() references a function __exit fcoe_transport_exit().
This is often seen when error handling in the init function uses functionality in the exit path.
The fix is often to remove the __exit annotation of fcoe_transport_exit() so it may be used outside an exit section.

Hi Sha,

    Thanks for the patch. I have seen this same change a few times. The warning has existed for the entirety of the 3.5 development cycle. It's currently in scsi.git/for-next. Take a look at this tread from linux-scsi for the discussion about it.
