Subject: why is "struct cdev *cdev" in char_device_struct listed as "will
 die"?


  just perusing fs/char_dev.c and noticed this:

static struct char_device_struct {
        struct char_device_struct *next;
        unsigned int major;
        unsigned int baseminor;
        int minorct;
        char name[64];
        struct cdev *cdev;              /* will die */
} *chrdevs[CHRDEV_MAJOR_HASH_SIZE];

  so ... why "will die"?  deprecated?  obsolete?
