If you target 5.7, remember that the merge window for 5.7 is already going on, and Linus is extremely cranky about pulling anything that hasn't stewed in next for a while. Your patchset hasn't been in next yet, so the timing is very very late. You'd need to bother Stephen Rothwell or someone who has a tree in next about right now to have any chances. > > Is it possible to mention that there might distro-specific changes > > needed to initramfs-handling? > > For Debian you are welcome to include below Link [1]. > > Not sure I will send/ask to/on the debian-kernel mailing list in this topic. > > I don’t expect any distro specific changes are required to continue operating > as-is.

Just setting COMPRESS=zstd is enough -- it'll say: W: Unknown compression command zstd but will do everything right.
