[CRIU] CRIU saving/restoring fd for the device file

[Zmudzinski, Krystof C]

Yes, the fd is restored but ioctls fail.  My driver is a misc character driver although I could probably change it to something else.  I haven’t figured out a way to reconnect the fd back to the driver.

Sir,
I am working on criu, i am not able to dump process tree because of fd of a device file.You have mentioned in your query of CRIU  mailing list that you were able to succesfully save/restore fd of a device file.
Can you tell me that how did you save fd of a file?

It will be a major step for me if i am able to store fd of a device file.

Thanks,
Nilesh
