Subject: Re: [PATCH 1 of 9] Lock the entire mm to prevent any mmu related operation to happen
Date: Wed, 16 Apr 2008 11:33:37 -0500 [thread overview]
Message-ID: <20080416163337.GJ22493@sgi.com> (raw)
In-Reply-To: <ec6d8f91b299cf26cce5.1207669444@duo.random>
I don't think this lock mechanism is completely working. I have
gotten a few failures trying to dereference 0x100100 which appears to
be LIST_POISON1.
Thanks,
Robin
