A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e1,e2; @@ ( if (\(ret < 0\|ret != 0\)) { ... return ret; } | ret = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall(a)lip6.fr&gt; --- drivers/staging/lustre/lnet/lnet/api-ni.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/staging/lustre/lnet/lnet/api-ni.c b/drivers/staging/lustre/lnet/lnet/api-ni.c index faceb95..4a14e51 100644 --- a/drivers/staging/lustre/lnet/lnet/api-ni.c +++ b/drivers/staging/lustre/lnet/lnet/api-ni.c @@ -650,15 +650,19 @@ lnet_prepare(lnet_pid_t requested_pid) recs = lnet_res_containers_create(LNET_COOKIE_TYPE_ME, LNET_FL_MAX_MES, sizeof(lnet_me_t)); - if (recs == NULL) + if (recs == NULL) { + rc = -ENOMEM; goto failed; + } the_lnet.ln_me_containers = recs; recs = lnet_res_containers_create(LNET_COOKIE_TYPE_MD, LNET_FL_MAX_MDS, sizeof(lnet_libmd_t)); - if (recs == NULL) + if (recs == NULL) { + rc = -ENOMEM; goto failed; + } the_lnet.ln_md_containers = recs;
