I suppose you can argue it removes one conditional if datum is NULL, but that is such a corner case I'm not worried about it. If I were to merge this, I would probably expect "kfree(datum)" to be converted to "kfree(comdatum)" (and similar in the cases below). > @@ -675,8 +675,8 @@ static int cls_destroy(void *key, void *datum, void *p) > kfree(ctemp); > } > kfree(cladatum->comkey); > + kfree(datum); > } > - kfree(datum); > return 0; > } > > @@ -689,8 +689,8 @@ static int role_destroy(void *key, void *datum, void *p) > role = datum; > ebitmap_destroy(&role->dominates); > ebitmap_destroy(&role->types); > + kfree(datum); > } > - kfree(datum); > return 0; > } > > @@ -712,8 +712,8 @@ static int user_destroy(void *key, void *datum, void *p) > ebitmap_destroy(&usrdatum->range.level[0].cat); > ebitmap_destroy(&usrdatum->range.level[1].cat); > ebitmap_destroy(&usrdatum->dfltlevel.cat); > + kfree(datum); > } > - kfree(datum); > return 0; > } > > @@ -726,8 +726,8 @@ static int sens_destroy(void *key, void *datum, void *p) > levdatum = datum; > ebitmap_destroy(&levdatum->level->cat); > kfree(levdatum->level); > + kfree(datum); > } > - kfree(datum); > return 0; > } > > -- > 2.11.0 > -- paul moore www.paul-moore.com -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
