And I've been considering that particular series WIP for two reasons:
1) Oleg was still unconvinced about patch 5/5 in the v2 discussion.
Upon re-reading it I think he might have come around and has agreed
to the current approach - but sending a v3 & not seeing Oleg object
would ascertain that.
2) There was a build failure reported against -v2 at:
https://lore.kernel.org/all/202410050745.2Nuvusy4-lkp@intel.com/t.mbox.gz
We cannot and will not merge patches with build failures.
Andrii did get some other uprobes scalability work merged in v6.13:
- Switch to RCU Tasks Trace flavor for better performance (Andrii Nakryiko)
- Massively increase uretprobe SMP scalability by SRCU-protecting
the uretprobe lifetime (Andrii Nakryiko)
So we've certainly not been ignoring his patches, to the contrary ...
Thanks,
Ingo
