It would be helpful to have a new field to hold names of shrinkers. This information would be useful while analyzing their behavior using tracepoints. --- include/linux/shrinker.h | 1 + 1 file changed, 1 insertion(+) diff --git a/include/linux/shrinker.h b/include/linux/shrinker.h index 4fcacd9..431125c 100644 --- a/include/linux/shrinker.h +++ b/include/linux/shrinker.h @@ -52,6 +52,7 @@ struct shrinker { unsigned long (*scan_objects)(struct shrinker *, struct shrink_control *sc); + const char *name; int seeks; /* seeks to recreate an obj */ long batch; /* reclaim batch size, 0 = default */ unsigned long flags; -- 2.7.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
