19b8e134c0dptrace: ban ptracing of a container init from inside the containerCurrent ptrace engine suffers from strange problems, one of which is described in bug #1222 - init results in T state after incorrect tracer detach. Fixing it is not that easy, but since ptracing init was never alowed before it's OK to ban this (for a while?). http://bugzilla.openvz.org/show_bug.cgi?id=1222 Signed-off-by: Pavel Emelyanov <xemul@openvz.org>

7e0f90d2f2dcfq: revalidate cached async queueAsync queues are stored on struct cfq_bc_data and are cached on per-process struct cfq_io_context. The cached queue may be invalid due to io_page beancounter driven io-context switch. So, cfq_io_context gets cached queue, but corresponding cfq_bc and user_beancounter may be already destroyed -- all this leads to oops at get_beancounter in cfq_set_request. Add check for async queue owner and ...
