So I guess we have an unexpressed dependency.
Did your config change from SLAB to SLUB or something? lib/zlib_inflate/infutil.c includes <linux/slab.h> but if your config changes, I'm guessing it doesn't work all that well if you change the allocator because those tracing functions are in <linux/sl{a,u}b_def.h>.
