Subject: Re: [GIT, RFC] Killing the Big Kernel Lock
Date: Thu, 25 Mar 2010 16:40:38 +0300 [thread overview]
Message-ID: <20100325134002.GA15851@bicker> (raw)
In-Reply-To: <201003242240.54907.arnd@arndb.de>
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.
