[PATCH 11/18] block: parse partition table on block device registration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Every instance where we register a block device, it's followed by an
attempt to parse the partition table, most often with a warning when
it fails. Thus let's move partition table parsing into
blockdevice_register.
