Note that the LZ4 signature is different than that of modern LZ4 as we use the "legacy" format which suffers from some downsides like inability to disable compression. Signed-off-by: Adam Borowski <kilobyte@angband.pl> --- The first time this was sent I managed to screw up both the subject and scissors line, so it's likely whatever filter you're using didn't notice the patch inside a thread. ZSTD compression for vmlinux is not yet in, but being able to unpack it can't hurt. LZ4 is in for quite a while. scripts/extract-vmlinux | 2 ++ 1 file changed, 2 insertions(+)
