Replying to my own message.
I assume this is because we have this in kernel:
/*
* The remap event
*/
struct blk_io_trace_remap {
__be32 device;
u32 __pad;
__be64 sector;
};
but this in blktrace:
/*
* The remap event
*/
struct blk_io_trace_remap {
__u32 device;
__u32 device_from;
__u64 sector;
};
Correct?
