Did you evaluate/tested destroy_dev_sched() KPI for your needs ? I do not see any protection for several opens going parallel on given cdev. I.e., I think that si_drv1 assignment in open() could cause problems. Generally, as I know, system does not enforce any serialization between calls to cdev methods for mp-safe drivers.
