We know that at lot of the drm people uses "dim fixes".
So maybe teach them a litte here?
diff --git a/dim b/dim
index e4f4d2e..d4fd310 100755
--- a/dim
+++ b/dim
@@ -2428,6 +2428,10 @@ function dim_fixes
sha1=${1:?$usage}
+ echo ""
+ echo "Note: Patch must meet the stable-kernel-rules criterias
(Documentation/process/stable-kernel-rules.rst)"
+ echo ""
+
cd $DIM_PREFIX/$DIM_REPO
echo "Fixes: $(dim_cite $sha1)"
Output would then look like this:
$ dim fixes 1d8d42ba365101fa68d210c0e2ed2bc9582fda6c
Note: Patch must meet the stable-kernel-rules criterias
(Documentation/process/stable-kernel-rules.rst)

No guarantee that people will look up the rules outlined in
stable-kernel-rules.rst - but at least a reminder.
