\n\tWARNING: \/home\/zausiu\/linux-3.0.66\/mm\/sksm\/sksm.o(.init.text+0x193): Section mismatch in reference from the function init_module() to the function .exit.text:sksm_slab_free()
\n\tThe function __init init_module() references
\n\ta function __exit sksm_slab_free().
\n\tThis is often seen when error handling in the init function
\n\tuses functionality in the exit path.
\n\tThe fix is often to remove the __exit annotation of
\n\tsksm_slab_free() so it may be used outside an exit section.<\/p>\n
