You are absolutely right, it doesn't make any sense. The 20 char limit
is bad, but really,
having the name duplicated in the device structure, while the name is
already in the
embedded kobject, is really bad.
Greg recently got rid of the 20 chars in the kobject, now we need to fix the
devices to completely get rid of the static bus_id string array, and just set
the kobject name directly.
It's all long overdue to fix things like this in the driver core -
it's such a mess. After the
kset cleanup Greg and I are doing currently, we will remove that silly limit.
Hmm, regardless of the limit, isn't there a better device name than a memory
address of a kernel structure. :) If there is no better data,
shouldn't we get something
like an atomic counter somewhere in the nfs code, which just increases
with every
instance, and we could use that number as a connection id?
