Whatever happened to adding a new flag to indicate that write
requests can be throttled, rather than overloading WRITE_SYNC with
yet another (conflicting) meaning?

I've already pointed out the problems associated with tagging async,
bulk writes as synchronous writes so that a lower layer can avoid
throttling them. Please add a new flag for communicating whether
writes can be throttled to the block layer instead of reusing
WRITE_SYNC.

Cheers,

Dave.
