There is a typo in this one:

commit 12c8fcce56c0de4fdcacf048fe723c8778af940d
Author: Arnd Bergmann <arnd@relay.de.ibm.com>
Date:   Wed Mar 24 20:08:55 2010 +0100

    block: replace BKL with global mutex
    
    It doesn't seem to interact with much else, so give
    this a try.

    Signed-off-by: Arnd Bergmann <arnd@arndb.de>
