+struct blk_user_trace_setup2 {
+ char name[32]; /* output */
+ __u64 act_mask; /* input */
+ __u32 buf_size; /* input */
+ __u32 buf_nr; /* input */
+ __u64 start_lba;
+ __u64 end_lba;
+ __u32 pid;
+ __u32 reserved; /* for futute use */I'd rename __reserved to flags, and check that it is zero, and then add a few more __u64 for extensibility.
