Could we please see complete description of the runtime effects of this
change?  How does it affect users?  How does it benefit users?

The DEVTMPFS_MOUNT Kconfig help (drivers/base/Kconfig) says:

	  This option does not affect initramfs based booting, here
	  the devtmpfs filesystem always needs to be mounted manually
	  after the rootfs is mounted.

which seems to no longer be correct?
