I think we need to stop somewhere, and claim th= at further issues needs to be fixed in that problematic third-party sources. It is not that FreeBSD change to add sched_get/setaffinity is unreasonable, right? The functionality is useful and simplifies porting a lot of stuff (I know this first-hand with ucx and tcmalloc examples), it is some cases where unreasonable assumptions are made that existence of that API implies Linux + glibc. I tried to get opinions of ports maintainers that are affected by the issue. I provided a mechanism like _WANT_CPU_SET_T that makes some incompatible API visibility optional. All I get in response was a silence. I do want to merge this sched.h changes and new API to stable/13, mostly because I want membarrier(2) and rseq(2). and sched changes a prerequisites. The M= FC would clearly require some coordination with Stefan to also get the follow-ups merged right after the base merge. It is up to ports to handle fallouts now, I believe. --=20 You are receiving this mail because: You are on the CC list for the bug.=
