Not a problem.
It's just a pain trying to figure out where the file 'private_data' is being
used.
$ git grep private_data | wc -w
37272
$ git grep private_data include | wc -w
1068
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.
Regards,
Hartley
