Ugh, and it doesn't play nice with static linking. I haven't tried running on a NUMA system yet, so maybe it's benign? /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/14/../../../x86_64-linux-gnu/libnuma.a(affinity.o): in function `affinity_ip': (.text+0x629): warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking _______________________________________________ Linux-f2fs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
