Make sure a poorly timed `rmmod transport` won't lead to a NULL/stale pointer dereference. Note that these oopses are pretty unlikely to happen in the wild. Splats were collected after sprinkling kernel with mdelay()s. v3: https://lore.kernel.org/20250702-vsock-transports-toctou-v3-0-0a7e2e692987@rbox.co v2: https://lore.kernel.org/20250620-vsock-transports-toctou-v2-0-02ebd20b1d03@rbox.co v1: https://lore.kernel.org/20250618-vsock-transports-toctou-v1-0-dd2d2ede9052@rbox.co ==================== Link: https://patch.msgid.link/20250703-vsock-transports-toctou-v4-0-98f0eb530747@rbox.co Signed-off-by: Jakub Kicinski --- 40c47232772e45385757e8c979d8871895c78823
