Is this about Liao's siglock patch set?

This one is about this patch set (speculative uprobe lookup), right? It is already at v4 ([1]), while you are mentioning v2 as the reason for this to not yet be applied. Those build failures were fixed *a long time ago*, v4 itself has been sitting idle for almost a month (since Oct 27). If there are any other problems, do bring them up, don't wait for weeks. > > 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 ... Yes, and as I mentioned, this one is a) ready, reviewed, tested and b) complements the other work you mention. It removes mmap_lock which limits scalability of the rest of the work.
