rxe_info_dev will finally call printk to output information.

In this link 
https://github.com/torvalds/linux/blob/master/Documentation/core-api/printk-basics.rst,
"
All printk() messages are printed to the kernel log buffer, which is a 
ring buffer exported to userspace through /dev/kmsg. The usual way to 
read it is using dmesg.
"
Do you mean that a new line will help the kernel log buffer flush 
message out?
