From a8b17ed019bd40d3bfa20439d9c36a99f9be9180 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 20 Jan 2011 16:38:27 +0000 Subject: KEYS: Do some style cleanup in the key management code. Do a bit of a style clean up in the key management code. No functional changes. Done using: perl -p -i -e 's!^/[*]*/\n!!' security/keys/*.c perl -p -i -e 's!} /[*] end [a-z0-9_]*[(][)] [*]/\n!}\n!' security/keys/*.c sed -i -s -e ": next" -e N -e 's/^\n[}]$/}/' -e t -e P -e 's/^.*\n//' -e "b next" security/keys/*.c To remove /*****/ lines, remove comments on the closing brace of a function to name the function and remove blank lines before the closing brace of a function.
