From 9d53dc48e885da95b60a12c1cbbce8d3ca5d7598 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Netto Date: Wed, 19 Oct 2022 19:14:31 -0300 Subject: Linux: Make generic fcntl.h the default one It is currently used for csky, arc, nios2, and or1k. Newer 64 bit architecture, like riscv32 and loongarch, reimplement it to override F_GETLK64/F_SETLK64/F_SETLKW64.
