Close race in md_probe There is a possible race in md_probe. If two threads call md_probe for the same device, then one could exit (having checked that ->gendisk exists) before the other has called kobject_init_and_add, thus returning an incomplete kobj which will cause problems when we try to add children to it. So extend the range of protection of disks_mutex slightly to avoid this possibility. Signed-off-by: Neil Brown <neilb@suse.de>
