It seems that this script is not in= voked by the build system. Any suggestion? Many thanks.

Hi guys,

I am a newbie in FreeBSD driver developm= ent. 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\dev= fs_devs.c). What I have missed? Many thank.
