Hi all!
There is an idea to make NBD protocol extension to support 64bit
write-zero/discard/block-status commands (commands, which doesn't
transfer user data). It's needed to increase performance of zeroing
large ranges (up to the whole image). Zeroing of the whole image is used
as first step of m

Any thoughts here? I need to resend to update some more functions as patchew
said.
Is it OK in general? Or should we instead convert everything to uint64_t ?

I definitely prefer int64_t as our base (off_t is signed as well, making

So, I think the simplest way is to add .bdrv_co_pwritev_zeros64 and
.bdrv_co_pdiscard64 and update drivers one-by-one. If at some point all
drivers updated - drop unused 32bit functions, and then drop "64" suffix
from API. If not - we'll li
