Unfortunately the <n> thing is part of the kernel ABI:

	echo "<4>foo" > /dev/kmsg

Which works the same way it did before.

I didn't say it didn't.

What I did say is that echo "\0014">/dev/kmsg will subvert the intent
of the new logging code.  Or might.  But you just ignored all that,
forcing me to repeat myself, irritatedly.

It works the same way before and after the patch.

Any write to /dev/kmsg without a KERN_<LEVEL>
emits at (1 << 3) + KERN_DEFAULT.

Writes with <n> values >= 8 are emitted at
that level.

What about writes starting with \001n?  AFACIT, that will be stripped
away and the printk level will be altered.  This is new behavior.
