Some functions in block/blk-core.c must only be used on blk-sq queues while others are safe to use against any queue type. Document which functions are intended for blk-sq queues and issue a warning if the blk-sq API is misused. This does not only help block driver authors but will also make it easier to remove the blk-sq code once that code is declared obsolete. Signed-off-by:
