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: Sumit Saxena <[email protected]> Signed-off-by: Fengguang Wu <[email protected]> --- megaraid_sas_fusion.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) --- a/drivers/scsi/megaraid/megaraid_sas_fusion.c +++ b/drivers/scsi/megaraid/megaraid_sas_fusion.c @@ -328,25 +328,22 @@ megasas_alloc_cmdlist_fusion(struct mega * Allocate the dynamic array first and then allocate individual * commands. */ - fusion->cmd_list = kmalloc(sizeof(struct megasas_cmd_fusion *) * max_cmd, - GFP_KERNEL); + fusion->cmd_list = kzalloc(sizeof(struct megasas_cmd_fusion *) * max_cmd, + GFP_KERNEL); if (!fusion->cmd_list) { dev_err(&instance->pdev->dev, "Failed from %s %d\n", __func__, __LINE__); return -ENOMEM; } - memset(fusion->cmd_list, 0, - sizeof(struct megasas_cmd_fusion *) * max_cmd); for (i = 0; i < max_cmd; i++) { - fusion->cmd_list[i] = kmalloc(sizeof(struct megasas_cmd_fusion), + fusion->cmd_list[i] = kzalloc(sizeof(struct megasas_cmd_fusion), GFP_KERNEL); if (!fusion->cmd_list[i]) { dev_err(&instance->pdev->dev, "Failed from %s %d\n", __func__, __LINE__); return -ENOMEM; } - memset(fusion->cmd_list[i], 0, sizeof(struct megasas_cmd_fusion)); } return 0; } -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
