    locking/rwsem: Provide down_write_killable() · 916633a4
    Michal Hocko authored
    Now that all the architectures implement the necessary glue code
    we can introduce down_write_killable(). The only difference wrt. regular
    down_write() is that the slow path waits in TASK_KILLABLE state and the
    interruption by the fatal signal is reported as -EINTR to the caller.
