The loop in __sk_stream_wait_memory when tcp_sendmsg asks to wait for

ptrace: ban ptracing of a container init from inside the containerCurrent ptrace engine suffers from strange problems, one of which

Fixing it is not that easy, but since ptracing init was never alowed
before it's OK to ban this (for a while?).

cfq: revalidate cached async queueAsync queues are stored on struct cfq_bc_data

USB: usbfs: keep async URBs until the device file is closedcommit 6ff10464096540e14d7575a72c50d0316d003714 upstream.
The usbfs driver manages a list of completed asynchronous URBs. But
it is too eager to free the entries on this list: destroy_async() gets
called whenever an interface is unbound or a device is removed, and it
deallocates the outstanding struct async entries for all URBs on that
