Hi,

The patch series aims to fix the races between nbd setup and module
removal which will lead to oops. Patch #1 serializes the concurrently
calling of nbd_genl_connect() and nbd_cleanup(), and patch #2 fixes
race between nbd_alloc_config() and nbd_cleanup().

Any comments are welcome.

Regards,
Tao
