https://github.com/numactl/numactl/commit/851bbd5b963a7a5d95b8fe3102cf05972dc72655.patch From: Khem Raj Date: Thu, 15 Dec 2022 12:11:13 -0800 Subject: [PATCH] shm.c: Replace stat64/fstat64/ftruncate64mmap64 with normal functions These functions were needed when _FILE_OFFSET_BITS was not 64, using AC_SYS_LARGEFILE will detect it correctly and make the normal variants of these functions behave same as their *64 counterparts.
