+Subject: [PATCH] Really fix spurious %transfiletriggerpostun execution
+ (RhBug:2023311)
+
+Commit b3d672a5523dfec033160e5cc866432a0e808649 got the base reasoning
+in the ballpark but the code all wrong, introducing a severe performance
+regression without actually fixing what it claimed to.
+
+The missing incredient is actually comparing the current prefix with the
+triggers in matched package (trying to describe this makes my head
+spin): a package may have multiple triggers on multiple prefixes and
+we need to make sure we only execute triggers of this type, from this
+prefix.
+
+Fixes: b3d672a5523dfec033160e5cc866432a0e808649
