From 4d0fe291aed3a476a3b59c4ecfae9d35ac0f15e8 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 24 May 2023 16:24:19 -0300 Subject: io: Fix record locking contants on 32 bit arch with 64 bit default time_t (BZ#30477) For architecture with default 64 bit time_t support, the kernel does not provide LFS and non-LFS values for F_GETLK, F_GETLK, and F_GETLK (the default value used for 64 bit architecture are used). This is might be considered an ABI break, but the currenct exported values is bogus anyway. The POSIX lockf is not affected since it is aliased to lockf64, which already uses the LFS values. Checked on i686-linux-gnu and the new tests on a riscv32.
