在 2023/8/23 10:13, Li Zhijian 写道:
A newline help flushing message out.

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?
