    ipc: store ipcs into IDRs · 7ca7e564
    Nadia Derbey authored
    This patch introduces ipcs storage into IDRs. The main changes are:
      . This ipc_ids structure is changed: the entries array is changed into a
        root idr structure.
      . The grow_ary() routine is removed: it is not needed anymore when adding
        an ipc structure, since we are now using the IDR facility.
      . The ipc_rmid() routine interface is changed:
           . there is no need for this routine to return the pointer passed in as
             argument: it is now declared as a void
           . since the id is now part of the kern_ipc_perm structure, no need to
             have it as an argument to the routine
