For non-F2FS systems, dm-bow must be enabled in the kernel config.

This paper suggests for the first time to leverage the address-remap technique in flash storage to remedy such pitfalls in F2FS.

F2FS was merged into the Linux 3. Separate hot and cold data.

For example, this limitation can manifest if the F2FS partition was created on a mainline kernel provided by linux yet the system has a need to downgrade to an older series of kernels. The file system builds on append-only logging and its key design decisions were made with the characteristics of flash storage in mind.
