mm-shrinker-make-shrinker-not-depend-on-memcg-kmem-fix.patch fixes
the compile-time error when memcg_expand_shrinker_maps() is not
declared, but now we get a linker error instead because the
function is still not built into the kernel:

mm/vmscan.o: In function `prealloc_shrinker':
vmscan.c:(.text+0x328): undefined reference to `memcg_expand_shrinker_maps'
