    what's the benefit of overloading the oom_control name here? It seems that you could make 'enable' an option and return a Try<bool> to roll the two methods together.

I changed the method to oom_control_enabled() with an Option<bool> to change state.

src/linux/cgroups.hpp
<https://reviews.apache.org/r/20137/#comment72695>

    What does this return? That is, what does the uint64_t represent and can we either add a comment (if it's useful) or convert it to Nothing() if it's an artifact of the listening technique?
    
    The name here might be a bit opaque. 'cgroups::memory::listen' doesn't really tell us what we're listening for.
    
    What about 'cgroups::memory::oomListen'? You'll notice the other methods here were named with snake case, this was to directly match the control file names.



src/linux/cgroups.cpp
<https://reviews.apache.org/r/20137/#comment72694>

    We should add a check for the format we expect:
    
    if (pairs.count("oom_kill_disable") != 1 ||
        pairs["oom_kill_disable"].empty()) {
      return Errror(...);
    }



src/slave/containerizer/isolators/cgroups/mem.cpp
<https://reviews.apache.org/r/20137/#comment72696>

    It's a bit unfortunate that the code is not that clear without the comments. We're passing 'true' into something called 'oom_control' which doesn't really tell us that we're enabling the oom killer. Seems like this is a place where the direct mapping from control names to function names is a bit unfortunate.
    
    I guess this is ok for now.

Ship it!


There's a bug that can crash the program, but otherwise looks good. Please go ahead and commit after addressing comments.


src/linux/cgroups.cpp
<https://reviews.apache.org/r/20137/#comment81189>

    You can't call .error() if 'exists' is false!



src/linux/cgroups.cpp
<https://reviews.apache.org/r/20137/#comment81190>

    How about:
    
    return pairs["oom_kill_disable"].front() == "0";



src/linux/cgroups.cpp
<https://reviews.apache.org/r/20137/#comment81191>

    Should this have an error prefix string like you did inside 'enabled' above?



src/linux/cgroups.cpp
<https://reviews.apache.org/r/20137/#comment81192>

    Ditto.

    Can we split this into two methods? An Option<bool> seems a bit weird.
    
    oom_control_enabled()
    
    and
    
    oom_control_enable()

It looks like the API could be made a little more clear here, see my comment below.


src/linux/cgroups.hpp
<https://reviews.apache.org/r/20137/#comment80385>

    I would suggest the following scheme:
    
    (1) Try<bool> enabled = memory::oom::killer::enabled(hierarchy, cgroup)
    (2) Try<Nothing> enable = memory::oom::killer::enable(hierarchy, cgroup)
    (3) Try<Nothing> disable = memory::oom::killer::disable(hierarchy, cgroup)
    (4) Future<Nothing> oom = memory::oom::listen(hierarchy, cgroup)
    
    Isn't it more intuitive to say "killer" than "control"? It also seems confusing to read the enable/disable cases as inquiries. Without the comment above the following code I'm not sure it would read intuitively:
    
    // Disable the oom killer.
    Try<bool> enabled = memory::oom_control_enabled(hierarchy, cgroup, false);
    
    
    I think our snake_case matching with the control file names breaks down now and we should move away from it. Let's do that later though:
    
    Try<Nothing> limit = memory::setLimit(hierarchy, cgroup, Megabytes(1));
    Try<Bytes> limit = memory::limit(hierarchy, cgroup);
    Try<Nothing> softLimit = memory::setSoftLimit(hierarchy, cgroup, Megabytes(1));
    Try<Bytes> softLimit = memory::softLimit(hierarchy, cgroup);
    Try<Bytes> usage = memory::usage(hierarchy, cgroup);
    Try<Bytes> usage = memory::maxUsage(hierarchy, cgroup);



src/linux/cgroups.cpp
<https://reviews.apache.org/r/20137/#comment80386>

    Does this need to be a Future<Nothing> or can it just be a Nothing?
