Move the io_stat flag into the queue_limits feature field so that it can be set atomically and all I/O is frozen when changing the flag.
Why a feature ? It seems more appropriate for io_stat to be a flag rather than a feature as that is a block layer thing rather than a device characteristic, no ?
Simplify md and dm to set the flag unconditionally instead of avoiding setting a simple flag for cases where it already is set by other means, which is a bit pointless. Signed-off-by: Christoph Hellwig <hch@xxxxxx>
