thanks for your reply,  from which verison of udev no longger creates
the device nodes?
I awaly use a very old udev. now I want upgrade udev to 182, but
failed,  should I enable
DEVTMPFS ?

and I had tried to build kernel with CONFIG_DEVTMPFS, and also cannot
find dynamic device node be created.
/ # zcat /proc/config.gz |grep CONFIG_DEVTMPFS
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
