You do both realize that this is just the file specific hint? Inode based hints
will still work fine for UFS.

Jens,
Thanks for this reply.
This whole patch series removes support for per-bio write_hint.
Without bio write_hint, F2FS won't be able to cascade Hot/Warm/Cold
information to SCSI / UFS driver.
This is my current understanding. I might be wrong but I don't think we
Are concerned with inode hint (as well as file hints).
But ufs/scsi doesn't use it in mainline, as far as I can tell. So how
does that work?
Hi Luca,
I'm not aware of any Android branch on which the UFS driver or the SCSI
core uses bi_write_hint or the struct request write_hint member. Did I
perhaps overlook something?
Thanks,
Bart.
