`sudo dmesg | grep -i kasan` comes back empty, at least confusing me.
So, include the abbreviation in the log line.

Before:

KernelAddressSanitizer initialized (generic)

After:

KernelAddressSanitizer (KASAN) initialized (generic)

I think a better change would be to add:

#define pr_fmt(fmt) "kasan: " fmt

to generic.c.

Similar to how this is done in sw/hw_tags.c.

Isn’t there only this one log line in `generic.c`, so the generalization is not really needed?

And arguably, we could also drop the "KernelAddressSanitizer" part
from init messages, to make them look like:

kasan: initialized (generic)
Some analysis scripts might already depend on KernelAddressSanitizer, so I’d keep it.


Kind regards,

Paul
