That doesn't sound correct to me. I think support for this API was added
in F2FS in November 2017 (commit 4f0a03d34dd4 ("f2fs: apply write hints
to select the type of segments for buffered write")). That was a few
months after NVMe stream support was added (June 2017) by commit
f5d118406247 ("nvme: add support for streams and directives").
Should NVMe streams be brought back? Yes? No?
From commit 561593a048d7 ("Merge tag 'for-5.18/write-streams-2022-03-18'
of git://git.kernel.dk/linux-block"): "This removes the write streams
support in NVMe. No vendor ever really shipped working support for this,
and they are not interested in supporting it."
I do not want to reopen the discussion about NVMe streams.
Thanks,
Bart.
