In this code, 0 is returned on memory allocation failure, even though other failures return -ENOMEM or other similar values. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ret; expression x,e1,e2,e3; @@ ret = 0 ... when != ret = e1 *x = \(kmalloc\|kcalloc\|kzalloc\)(...) ... when != ret = e2 if (x == NULL) { ... when != ret = e3 return ret; } // </smpl> Signed-off-by: Julia Lawall <[email protected]> To: Pat Gefre <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] Patchwork: https://patchwork.linux-mips.org/patch/1704/ Signed-off-by: Ralf Baechle <[email protected]>
