Hello all, I have a custom kernel module driver that returns a truncated 64-bit value. The first 32-bits are missing.
The driver is called using llseek() and the address used in user space and in kernel space is 64-bits, but when returning from kernel space, the first 32-bits gets truncated, only returning the second half. I've used printk on the address value before returning it in the driver and it is the full 64-bit address. The return is using loff_t, and I'm using a genericx86-64 Linux kernel. Any thoughts? Thanks, ----------------------------- Anthony B. Padua
