To make them available to lttng in NixOS, add this to configuration.nix:

  boot.extraModulePackages = [ pkgs.linuxPackages.lttngModules ];

because a check for existing ext3/*h files in the kernel build tree is skipped
for linux < 3.4. Fix it by extending the ext3_dep_check thing to also be run
when building against linux >= 3.2 (not only linux >= 3.4).
