bdi: introduce BDI_CAP_SYNCHRONOUS_IO ...
As discussed at
https://lkml.kernel.org/r/ <20170728165604.10455-1-ross.zwisler@linux.intel.com>
someday we will remove rw_page(). If so, we need something to detect
such super-fast storage on which synchronous IO operations like the
current rw_page are always a win.
Introduces BDI_CAP_SYNCHRONOUS_IO to indicate such devices. With it, we
could use various optimization techniques.
