[Hans Reiser <reiser@namesys.com>]

Signed-off-by: Hans Reiser

> 1. re-phrase "disabling write barrier" warning which confuses users and
>
>>   make it KERN_NOTICE instead of KERN_WARNING.
>> 2. remove the "[nikita-38210]: WARNING: stale dk" at
>> fs/reiser4/search.c   which does not indicate any reiser4 tree or fs
>> problems.
