    [PATCH] sysfs: fs/sysfs/inode.c: modify parents ctime and mtime on creation

    When a node is added to sysfs (e.g. a device plugged in via USB), the
    filesystem fails to make this change visible in the parent directory's
    ctime/mtime. This is in contrast to removing a device, because in that
    case, sysfs makes use of the function simple_unlink from fs/libfs.c which
    takes care of that. Instead of using simple_link from fs/libfs.c on
    creation, sysfs implements its own mechanism. This patch hooks into the
    function sysfs_create and sets the ctime and the mtime of the parent to
    CURRENT_TIME.
