[LSF/MM/BPF TOPIC] : Flexible Data Placement (FDP) availability for kernel space file systems

[Viacheslav Dubeyko]

Hi Javier,

Samsung introduced Flexible Data Placement (FDP) technology
pretty recently. As far as I know, currently, this technology
is available for user-space solutions only. I assume it will be
good to have discussion how kernel-space file systems could
work with SSDs that support FDP technology by employing
FDP benefits.

How soon FDP API will be available for kernel-space file systems?
How kernel-space file systems can adopt FDP technology?
How FDP technology can improve efficiency and reliability of
kernel-space file system?
Which new challenges FDP technology introduces for kernel-space
file systems?

Could we have such discussion leading from Samsung side?

Thanks,
Slava
