We have been iterating in the patches for years, but it is unfortunately
one of these series that go in circles forever. I don't think it is due
to any specific problem, but mostly due to unaligned requests form
different folks reviewing. Last time I talked to Damien he asked me to
send the patches again; we have not followed through due to bandwidth.
A big problem is that it actually lacks a killer use case. If you'd
actually manage to plug it into an in-kernel user and show a real
speedup people might actually be interested in it and help optimizing
for it.
Agree. Initially it was all about ZNS. Seems ZUFS can use it.
Then we saw good results in offload to target on NVMe-OF, similar to
copy_file_range, but that does not seem to be enough. You seem to
indicacte too that XFS can use it for GC.
We can try putting a new series out to see where we are...
