Linus,

I'm not sure what's going on here, this patch set seems to be in some
sort of "ignore list" on Peter's side with no indication on its
destiny.

*sigh* it is not, but my inbox is like drinking from a firehose :/

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 (local)

    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
