  • 5216d530b   locking/lockdep: Mark __lockdep_count_forward_deps() as static ... Browse Code »

    There are new Sparse warnings:

    >> kernel/locking/lockdep.c:1235:15: sparse: symbol '__lockdep_count_forward_deps' was not declared. Should it be static?
    >> kernel/locking/lockdep.c:1261:15: sparse: symbol '__lockdep_count_backward_deps' was not declared. Should it be static?

    Please consider folding the attached diff :-)

    My compiler refuses to actually say that; but it looks wrong in that
    do_div() returns the remainder, not the divisor.
