    Subject[git pull] pull request for writable limits for 2.6.34-rc0

    please pull the writable limits tree below.

    I'm not sure why you didn't pull it in the .33 window. I just guess
    there was no reasoning about why you would do so. So, what are the
    writable limits good for and why we are about to ship it in the next
    Suse enterprise?

    Conceivably, there are companies out there (such as SAP) running their
    large-scale products on Linux and eventually they need to change a limit
    without restarting the service. It is because restarting is not an
    option most of the time. The limits are needed to be changed usually
    because (a) it is not known in advance that some limits will need to
    have a different value; (b) some processes start to crash occasionally.
    In both cases the only necessity is just to change the particular limit
    (core size in case of (b)) in runtime.

    Hence we provide the functionality in the tree below. Opposing to the
    last merge, most of the cleanup stuff was already merged by respective
    maintainers into their trees rather than being here and are on the way
    to you. They are independent of this merge and just ensure that future
    compiler releases won't do weird things with the code.
