H A Dwrite-threshold.h94783301 Thu May 06 09:06:14 GMT 2021 Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> block/write-threshold: don't use write notifiers

write-notifiers are used only for write-threshold. New code for such
purpose should create filters.

Let's better special-case write-threshold and drop write notifiers at
all. (Actually, write-threshold is special-cased anyway, as the only
user of write-notifiers)

So, create a new direct interface for bdrv_co_write_req_prepare() and
drop all write-notifier related logic from write-threshold.c.
