I was also thinking about some new BLKPG-like ioctl()s. Could you please elaborate more on your new ioctl() proposal? Perhaps we could combine the ideas... Features of the new ioctl()/s I was thinking about are: - get largest number of partition known to the kernel - atomically add/remove more than one partition Regards, Petr -- Petr Uzel IRC: ptr_uzl @ freenode
