Created attachment 205154 [details] The patch file If the kernel is create with option MD_ROOT, g_md_init will call md_preload and use mfs_root as the image. In function md_preload, the address of image will be printed out. In this case, the address of image is the address of a global object mfs_root. A kernel leakage happens. Fix this by making this printing only happen when md_debug > 0.
