Message-ID: <20031118110139.45f2be60.akpm@osdl.org> (raw)
In-Reply-To: <6.0.1.1.2.20031118232152.01ae5728@tornado.reub.net>
It's one for the networking guys.
The mm kernels have a patch which detects when atomic_dec_and_test
takes an atomic_t negative - it is assumed that this is a bug so
a warning is generated.
