So your code allows me to use a partition block device (like sda2) to
register with the blkdev LED trigger, but when I do this, the code will
disregard that I just want the LED to blink on activity on that one
partition. Instead you will blink for whole sda, since you are looking
at stats of only part0.
Am I right?
You can't add partitions, only whole devices.
# echo vda2 > link_device
-bash: echo: write error: No such device
static int blkdev_match_name(struct device *const dev, const void *const
name)
{
return dev->type == &disk_type
&& sysfs_streq(dev_to_disk(dev)->disk_name, name);
}
Partitions fail the dev->type == &disk_type check.
