Hi,
I noticed zstd compression was recently added for btrfs and squashfs.
Are there actually already patches floating around for zstd kernel and intird
compression?
Looks like that would be a quite nice fit regarding speed and compression
ratio, …

René
I started working on some patches yesterday, and just got zstd kernel,
initrd, and initramfs compression working today. I think I'll be ready to
send the patches out within a week.
awesome, if you have something to test I could give it a try on my test bench,
too.
Here is a preview of the patch, though its not quite ready.
I believe it works, but I still need to clean it up a bit, and split it
into the decompression function, the initrd piece, and the x86 specific
piece. I'll try to get the patch set out this week, and I'll CC you.
thanks for the preview, which I applied cleanly, modulo this white-space
chunk:
diff --git a/lib/Kconfig b/lib/Kconfig

to the 4.14-rc2 tarball and it compiled and booted on x86-64,
including a zstd initrd!
Great work, will probably start testing it on my personal
laptop, to use the same compression everywhere.
Regards,
René
