    Not a problem.

    It's just a pain trying to figure out where the file 'private_data' is being

    $ git grep private_data | wc -w
    $ git grep private_data include | wc -w

    The following struct's all have a 'void *private_data' symbol in include/linux:

    struct ac97_codec
    struct c2port_device
    struct file
    struct gendisk
    struct ata_host
    struct ata_queued_cmd
    struct ata_device
    struct ata_port
    struct ata_port_info
    struct parport
    struct rchan
    struct rtc_task
    struct plat_serial8250_port
    struct uart_port

    include/rdma and include/sound also have a number.

    Thanks for the reply.
