Unlink a node from whatever list it is in. Nodes that are not part of a list must not be passed to this function! Assembly programmers may prefer to use the REMOVE macro from
exec/lists.i. The REMOVE() macro from <exec/list_macros.h> is available for 'C' programmers.
This function does not arbitrate for access to the list. The calling Task must be the owner of the involved list.
