Hi ,
following code snippet is self evident in what it does -
truct net_device *alloc_netdev(int sizeof_priv, const char *name,
void (*setup)(struct net_device *))
{
void *p;
struct net_device *dev;
int alloc_size;
/* ensure 32-byte alignment of both the device and private area */
alloc_size = (sizeof(*dev) + NETDEV_ALIGN_CONST) & ~NETDEV_ALIGN_CONST;
alloc_size += sizeof_priv + NETDEV_ALIGN_CONST;
p = kzalloc(alloc_size, GFP_KERNEL);
if (!p) {
printk(KERN_ERR "alloc_dev: Unable to allocate device.\n");
return NULL;
}
[snip]
Is the comment correct?
Why is it 'ensure 32 byte alignment', instead of 32 bit alignment?
What am i missing here?
Thank you
