Race condition between do_compile_kernelmodules and do_shared_workdir tasks occurs when do_compile_kernelmodules changes files in include/generated/* while do_shared_workdir tries to copy them to shared working directory.
Functionality of do_shared_workdir has been moved to separate function mk_shared_workdir and called from do_compile_kernelmodules. do_shared_workdir is left in the code as it may be used in many recipes.
