               boolean committed,
               int arena_ind)
        Extent split hook.

        An extent split function conforms to the extent_split_t type and optionally splits an extent at given addr and size into two adjacent extents, the first of size_a bytes, and the second of size_b bytes, operating on committed/decommitted memory as indicated, on behalf of arena arena_ind, returning false upon success. If the function returns true, this indicates that the extent remains unsplit and therefore should continue to be operated on as a whole.

        Parameters:
        extent_hooks -
        addr -
        size -
        size_a -
        size_b -
        committed -
        arena_ind -
