Subject: [PATCH] kvm-userland mm count skew
Date: Mon, 21 Jan 2008 13:44:55 +0100 [thread overview]
Message-ID: <20080121124455.GI6970@v2.random> (raw)
I still can't see how it could be possibly make a difference for the
mm_count if the kvm module is compiled inside the kernel or as an
external module, the reference counting there hasn't changed since
ages. The mmdrop fires only in the first overflow so even if I'm right
it probably wasn't much destabilizing to go negative given it happened
at mm destruction time.
