    headers: untangle kmemleak.h from mm.h · 514c6032
    Randy Dunlap authored
    Currently <linux/slab.h> #includes <linux/kmemleak.h> for no obvious
    reason.  It looks like it's only a convenience, so remove kmemleak.h
    from slab.h and add <linux/kmemleak.h> to any users of kmemleak_* that
    don't already #include it.  Also remove <linux/kmemleak.h> from source
    files that do not use it.
    
    This is tested on i386 allmodconfig and x86_64 allmodconfig.  It would
    be good to run it through the 0day bot for other $ARCHes.  I have
    neither the horsepower nor the storage space for the other $ARCHes.
    
    Update: This patch has been extensively build-tested by both the 0day
    bot & kisskb/ozlabs build farms.  Both of them reported 2 build failures
    for which patches are included here (in v2).
    
    [ slab.h is the second most used header file after module.h; kernel.h is
      right there with slab.h. There could be some minor error in the
      counting due to some #includes having comments after them and I didn't
      combine all of those. ]
