    Subject[PATCH v2 0/9] sysctl: first set of kernel/sysctl cleanups
    Date
    Finally had time to respin the series of the work we had started
    last year on cleaning up the kernel/sysct.c kitchen sink. People keeps
    stuffing their sysctls in that file and this creates a maintenance
    burden. So this effort is aimed at placing sysctls where they actually
    belong.

    I'm going to split patches up into series as there is quite a bit
    of work.

    This first set adds register_sysctl_init() for uses of registerting a
    sysctl on the init path, adds const where missing to a few places, generalizes
    common values so to be more easy to share, and starts the move of a
    few kernel/sysctl.c out where they belong.

    The majority of rework on v2 in this first patch set is 0-day fixes.
    Eric W. Biederman's feedback is later addressed in subsequent patch
    sets.

    I'll only post the first two patch sets for now. We can address the
    rest once the first two patch sets get completely reviewed / Acked.
    Since the sysctls are all over the place I can either put up a tree
    to keep track of these changes and later send a pull request to Linus
    or we can have them trickle into Andrew's tree. Let me know what folks
    prefer.

    Changes in v2:

    * 0-day compile issues
    * added reviewed-by tags
    * enhanced commit logs
    * Added patch by Stephen Kitt
