Hi Coly, We use 4.19.y and there have been many performance and stability changes since then. I'm considering backporting the 5.4 version into 4.19 and wondered: Are there any changes in bcache between 4.19 and 5.4 that depend on new features elsewhere in the kernel, or should I basically be able to copy the tree from 5.4 to 4.19 and fix minor compilation issues? Can you think of any issues that would arise from such a backport? -- Eric Wheeler
