Hello,
kernel test robot noticed a 1.9% improvement of stress-ng.dup.ops_per_sec on:

This is interesting approach. But I doubt we need to add additional
syscall just for this purpose. Can't we use another syscall or ioctl?
Also, we should run

VDPA_GET_VRING_SIZE by mistake uses the already occupied
ioctl # 0x80 and we never noticed - it happens to work
because the direction and size are different, but confuses
tools such as perf which like to look at just the number,
and breaks the extra robustness of the ioctl numbering macros.

Adding uretprobe syscall instead of trap to speed up return probe.
At the moment the uretprobe setup/path is:
- install entry uprobe
- when the uprobe is hit, it overwrites probed function's return address
on stack with address of the trampoline that contains breakpoint
instruction
hi,
as part of the effort on speeding up the uprobes [0] coming with
return uprobe optimization by using syscall instead of the trap
on the uretprobe trampoline.
The speed up depends on instruction type that uprobe is installed
and depends on specific HW type, please check patch 1 for details.
