If a device appears while module is being removed, driver will get a callback after we've given up on the major number. In theory this means this major number can get reused by something else, resulting in a conflict. To fix, cleanup in reverse order of initialization. Signed-off-by: Michael S.

This patch series renames "sd_format_disk_name()" to "disk_name_format()" and moves it into block core. So that who needs formatting disk name can use it, instead of duplicating these similar help functions. Ren Mingxin (4): block: add function disk_name_format() into block core scsi: replace sd_format_disk_name() to disk_name_format() block: replace

Rusty, currently virtio_blk uses one major number per device. While this works quite well on most systems it is wasteful and will exhaust major numbers on larger installations. This patch allocates a major number on init and will use 16 minor numbers for each disk. That will allow ~64k virtio_blk disks. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> ---
