Subject: KEYS: output last portion of fingerprint in /proc/keys
X-Git-Tag: v5.15~16679^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d4016589855156b6afe5e9bc8ef85ce43f27e704;p=platform%2Fkernel%2Flinux-starfive.git

KEYS: output last portion of fingerprint in /proc/keys

Previous version of KEYS used to output last 4 bytes of fingerprint.
Now it outputs 8 last bytes of raw subject, which does not make any
visual meaning at all. This patch restores old behavior.
