[PATCH] blk-mq: Avoid race condition with uninitialized requests
This patch should fix the bug reported in https://lkml.org/lkml/2014/9/11/249.
We have to initialize at least the atomic_flags and the cmd_flags when
allocating storage for the requests.
Otherwise blk_mq_timeout_check() might dereference uninitialized pointers when
racing with the creation of a request.
Also move the reset of cmd_flags for the initializing code to the point where a
request is
