F2FS Data Compression Using LZO/LZ4 + Selective File Extension Handling To Land In 2020

It's weird how each FS needs to implement this instead of having some generic layer doing it for all.

It's probably harder to make a generic interface for this generic layer (and the generic layer itself) with decent performance than adding FS-specific code to have compression support in the FS.

Yeah, maybe that's it, but it still seems like a bad choice to me.

a bad choice made by all filesystems in existence.

SO, F2FS on NVME!

[arokh]

LVM adds much overhead and this kills one of the purposes of F2FS.

Please elaborate on how you came to that conclusion.
