NAME
       fence_remove_callback - remove a callback from the signaling list

SYNOPSIS
       bool fence_remove_callback(struct fence * fence, struct fence_cb * cb);

ARGUMENTS
       fence
           [in] the fence to wait on

       cb
           [in] the callback to remove

DESCRIPTION
       Remove a previously queued callback from the fence. This function returns true if the
       callback is successfully removed, or false if the fence has already been signaled.

       *WARNING*: Cancelling a callback should only be done if you really know what you're doing,
       since deadlocks and race conditions could occur all too easily. For this reason, it should
       only ever be done on hardware lockup recovery, with a reference held to the fence.
