This patch reduces the kernel size by removing error messages that duplicate the normal OOM message.
A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr) @@ identifier f,print,l; expression e; constant char[] c; @@ e = \(kzalloc\|kmalloc\|devm_kzalloc\|devm_kmalloc\)(...); if (e == NULL) { <+... - print(...,c,...); ... when any ( goto l; | return ...; ) ...+> } Signed-off-by: Quentin Lambert <lambert.quen...@gmail.com> --- drivers/staging/rtl8192e/rtllib_module.c | 10 +++------- drivers/staging/rtl8192e/rtllib_rx.c | 11 ++++------- 2 files changed, 7 insertions(+), 14 deletions(-) diff --git a/drivers/staging/rtl8192e/rtllib_module.c b/drivers/staging/rtl8192e/rtllib_module.c index 248cc0d..32cc8df 100644 --- a/drivers/staging/rtl8192e/rtllib_module.c +++ b/drivers/staging/rtl8192e/rtllib_module.c @@ -72,11 +72,8 @@ static inline int rtllib_networks_allocate(struct rtllib_device *ieee) ieee->networks = kzalloc( MAX_NETWORK_COUNT * sizeof(struct rtllib_network), GFP_KERNEL); - if (!ieee->networks) { - printk(KERN_WARNING "%s: Out of memory allocating beacons\n", - ieee->dev->name); + if (!ieee->networks) return -ENOMEM; - } return 0; } @@ -161,10 +158,9 @@ struct net_device *alloc_rtllib(int sizeof_priv) rtllib_softmac_init(ieee); ieee->pHTInfo = kzalloc(sizeof(struct rt_hi_throughput), GFP_KERNEL); - if (ieee->pHTInfo == NULL) { - RTLLIB_DEBUG(RTLLIB_DL_ERR, "can't alloc memory for HTInfo\n"); + if (ieee->pHTInfo == NULL) return NULL; - } + HTUpdateDefaultSetting(ieee); HTInitializeHTInfo(ieee); TSInitialize(ieee); diff --git a/drivers/staging/rtl8192e/rtllib_rx.c b/drivers/staging/rtl8192e/rtllib_rx.c index 1664040..0a9cf44 100644 --- a/drivers/staging/rtl8192e/rtllib_rx.c +++ b/drivers/staging/rtl8192e/rtllib_rx.c @@ -394,10 +394,9 @@ static int is_duplicate_packet(struct rtllib_device *ieee, } if (p == &ieee->ibss_mac_hash[index]) { entry = kmalloc(sizeof(struct ieee_ibss_seq), GFP_ATOMIC); - if (!entry) { - printk(KERN_WARNING "Cannot malloc new mac entry\n"); + if (!entry) return 0; - } + memcpy(entry->mac, mac, ETH_ALEN); entry->seq_num[tid] = seq; entry->frag_num[tid] = frag; @@ -1345,11 +1344,9 @@ static int rtllib_rx_InfraAdhoc(struct rtllib_device *ieee, struct sk_buff *skb, /* skb: hdr + (possible reassembled) full plaintext payload */ payload = skb->data + hdrlen; rxb = kmalloc(sizeof(struct rtllib_rxb), GFP_ATOMIC); - if (rxb == NULL) { - RTLLIB_DEBUG(RTLLIB_DL_ERR, - "%s(): kmalloc rxb error\n", __func__); + if (rxb == NULL) goto rx_dropped; - } + /* to parse amsdu packets */ /* qos data packets & reserved bit is 1 */ if (parse_subframe(ieee, skb, rx_stats, rxb, src, dst) == 0) { -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
