or y'alls


Please make patches against 2.6.12-rcX, not against 2.6.11.z.
(probably doesn't matter in this case)


+struct aoedev *
+aoedev_bymajor_minor(ulong major, ulong minor)
+{

Kernel preferred style is not to split the function definition line.


+#ifdef CONFIG_ATA_OVER_ETH_ROOT
+#include <linux/delay.h>
+#include <linux/rtnetlink.h>
+#include <linux/netdevice.h>
+#include <net/sock.h>
+#endif

Lose the ifdef/endif. Don't make #includes conditional.

+printk("Bring up loopback...\n");
+ if (dev_change_flags(&loopback_dev, loopback_dev.flags | IFF_UP) < 0)
+ printk(KERN_ERR "AOE Root: Failed to open %s\n", loopback_dev.name);
+
+ /* Setup all network devices */
+ for (dev = dev_base; dev ; dev = dev->next) {
+ if (dev == &loopback_dev)
+ continue;
+printk("Bring up %s...\n",dev->name);

Did you mean to leave these printk()s here?
I think not, but if so, they need a KERN_ level, like KERN_INFO.


It would help readability if you would add some spaces around
'=', after commas, etc., in places like these:

+ for (d=devlist; d; d=d->next)
and
+ } while (!aoedev_bymajor_minor(CONFIG_ATA_OVER_ETH_ROOT_SHELF,CONFIG_ATA_OVER_ETH_ROOT_SLOT));
and
+ aoe_root(CONFIG_ATA_OVER_ETH_ROOT_SHELF,CONFIG_ATA_OVER_ETH_ROOT_SLOT);


Thanks.
