The kernel writes to swap files on f2fs directly without the assistance of the filesystem. This direct write by kernel can be non-sequential even when the f2fs is in LFS mode. Such non-sequential write conflicts with the LFS semantics. Especially when f2fs is set up on zoned block devices, the non-sequential write causes unaligned write command errors.To avoid the non-sequential writes to swap files, prevent swap file activation when the filesystem is in LFS mode.
