nfsd: getattr for FATTR4_WORD0_FILES_AVAIL needs the statfs buffer

Note nobody's ever noticed because the typical client probably never
requests FILES_AVAIL without also requesting something else on the list.

block: ensure that the timer is always added

If the timer isn't pending, we always need to add it.

blk-mq: remember to start timeout handler for direct queue

Commit 07068d5b8e added a direct-to-hw-queue mode, but this mode
needs to remember to add the request timeout handler as well.
Without it, we don't track timeouts for these requests.

mlx4_core: Move handling of MLX4_QP_ST_MLX to proper switch statement

The handling of MLX4_QP_ST_MLX in verify_qp_parameters() was
accidentally put inside the inner switch statement (that handles which
transition of RC/UC/XRC QPs is happening).  Fix this by moving the case
to the outer switch statement.

The compiler pointed this out with:

    drivers/net/ethernet/mellanox/mlx4/resource_tracker.c: In function 'verify_qp_parameters':
 >> drivers/net/ethernet/mellanox/mlx4/resource_tracker.c:2875:3: warning: case value '7' not in enumerated type 'enum qp_transition' [-Wswitch]

blk-mq: push IPI or local end_io decision to __blk_mq_complete_request()

We have callers outside of the blk-mq proper (like timeouts) that
want to call __blk_mq_complete_request(), so rename the function
and put the decision code for whether to use ->softirq_done_fn
or blk_mq_endio() into __blk_mq_complete_request().

This also makes the interface more logical again.
blk_mq_complete_request() attempts to atomically mark the request
completed, and calls __blk_mq_complete_request() if successful.
__blk_mq_complete_request() then just ends the request.
