I am still totally confused at when is `populate_rootfs` called.

Hi Jiahao,
Have you tried enabling tracing (ftrace IIRC) in the kernel to figure that out? Another possibility is to use Doxygen's call graphs, make sure you restrict the
analysis to minimum set of files you need (just remove all irrelevant
architecures and driver directories from doxygen's input, or extract them from your kernel image. I did some experiments on the topic some time ago, it might prove useful: https://bitbucket.org/hchaumette/linux_doxygen/src/master/.
Anyone interested can ask for access.)
