Subject: [PATCH resend] scripts: teach extract-vmlinux about LZ4 and ZSTD
Date: Sat, 7 Jul 2018 02:15:48 +0200 [thread overview]
Message-ID: <20180707001548.21854-1-kilobyte@angband.pl> (raw)
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.
