#include <sys/param.h>

#include <sys/vnode.h>

VOP_REVOKE() will administratively revoke access to the device specified by vp, as well as any aliases created via make_dev_alias(9). Further file operations on any of these devices by processes which have them open will nominally fail. The flags must be set to REVOKEALL to signify that all access will be revoked; any other value is invalid.
