In each case, the kfree already at the end of the function is also needed in the error case. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression x; statement S,S1; expression E; identifier fl; expression *ptr != NULL; @@ x = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...kfree(x)...+> } when any when != true x == NULL x->fl ...> ( if (x == NULL) S1 | if (...) { ... when != x when forall ( return \(0\|<+...x...+>\|ptr\); | * return ...; ) } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: John W.
