drivers/scsi/storvsc_drv.c:1500:13-20: WARNING: kzalloc should be used for payload, instead of kmalloc/memset Use kzalloc rather than kmalloc followed by memset with 0 This considers some simple cases that are common and easy to validate Note in particular that there are no ...s in the rule, so all of the matched code has to be contiguous Generated by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci CC: Cathy Avery <cavery@xxxxxxxxxx> Signed-off-by: Fengguang Wu <fengguang.wu@xxxxxxxxx> --- storvsc_drv.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) --- a/drivers/scsi/storvsc_drv.c +++ b/drivers/scsi/storvsc_drv.c @@ -1497,10 +1497,9 @@ static int storvsc_queuecommand(struct S payload_sz = (sg_count * sizeof(u64) + sizeof(struct vmbus_packet_mpb_array)); - payload = kmalloc(payload_sz, GFP_ATOMIC); + payload = kzalloc(payload_sz, GFP_ATOMIC); if (!payload) return SCSI_MLQUEUE_DEVICE_BUSY; - memset(payload, 0, payload_sz); } payload->range.len = length; _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
