NAME

VOP_REVOKE - revoke access to a device and its aliases

SYNOPSIS

In sys/param.h In sys/vnode.h Ft int Fn VOP_REVOKE struct vnode *vp int flags

DESCRIPTION

Fn VOP_REVOKE will administratively revoke access to the device specified by Fa vp , as well as any aliases created via make_dev_alias9. Further file operations on any of these devices by processes which have them open will nominally fail. The Fa flags must be set to REVOKEALL to signify that all access will be revoked; any other value is invalid.

LOCKS

The Fa vp must be unlocked on entry, and will remain unlocked upon return.
