Those are two separate issues. Firstly, usb-storage is not a block device drivers; it is a USB driver. The actual block device driver is part of the SCSI stack (because USB mass-storage devices use SCSI command sets). Secondly, the block driver (not device) is not aware when any of the filesystems in any of the partitions has been mounted. But it is aware of when the device file is open. > I mean: does the kernel > only keep a single link from the filesystem to the block device, > and nothing the other way around? A block device can contain many filesystems: one in each partition.
