Don't want to see "Assuming drive cache: write through" errors

Every time I attach an usb stick, I see some messages like this written to the errors.log:

sd 4:0:0:0: [sdc] Assuming drive cache: write through

It's very annoying to way through all these messages while reading errors.log

According to the http://lists.us.dell.com/fom-serve/cache/110.html this isn't actually an error. But if it isn't, why do these message are written to errors.log?

There is definitely something wrong.

Summary:

If it's an error, how do I fix this?
If it isn't an error, why are those messages written to errors.log (looks like a bug)?

Thanks.

Should I report this at the bugzilla.kernel.org or this is an arch-specific bug?

Re: Don't want to see "Assuming drive cache: write through" errors

the important thing to mention is your syslog config.
Ie this part:

destination d_errors { file("/var/log/errors.log"); };
(...)
g { source(src); filter(f_err); destination(d_errors); };

so these messages are f_err, which is weird
