    Well, I am not very concerned with the "changing by sysfs" leak. This is
    not a big deal, IMHO. I am concerned with the "rmmod" leak, which did
    not exist before your patches, but exists now. People may do a lot of
    insmod/rmmod, and on each rmmod they will loose this kstrdup-ed string.

    I'll take a look at this tree, thank you.

    Just in case others will clone, the correct URL seems to be

    git:// master
