DESCRIPTION

14       keyctl_invalidate()  invalidates a key.  The key is scheduled for imme‐
15       diate removal from all the keyrings that point to it,  after  which  it
16       will  be  deleted.   The  key will be ignored by all searches once this
17       function is called even if it is not yet fully dealt with.
18
19       The caller must have search permission on a key to be able  to  invali‐
20       date it.
