    Subject[PATCH REBASED 0/6] rwsem: Implement down_read_killable()
    From
    Date
    Hi,

    this is resending of the series, I previously sent. There are no changes
    in separate patches except of [4/6], which is rebased on recent tip.git.

    Two patches from the previous sending are already applied by Peter,
    so they are not in this series. They are:
    83ced169d9a0 "locking/rwsem-xadd: Add killable versions of rwsem_down_read_failed()" and
    0aa1125fa8bc "locking/rwsem-spinlock: Add killable versions of __down_read()"

    Also, there is one patch more [6/6], which was sent separate in
    the reply to the first series.

    So, there is no changes (except [4/6]). Please, take a look.

    The series introduces new down_read_killable() primitive, which
    is similar to down_read(), but it may be interrupted by a signal.
    The most touched is architectures code. Also, it marks a new user
    of the primitive, which is iterate_dir().
