I’m sorry. I’ve found it will be detached from cdevp_list in devfs_revoke.

主题: about devfs_free

Hi guys,
I am a newbie in FreeBSD driver development. I found that devfs_free(sys\fs\devfs\devfs_devs.c) does not detach the cdev_priv from the cdevp_list before free it. cdev_priv is inserted into cdevp_list in devfs_create(sys\fs\devfs\devfs_devs.c). What I have missed? Many thank.
