From b7ccb5de359e8dd9918dbedfc1f4d96e06fcd634 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Mon, 29 Jan 2018 16:12:08 +0000 Subject: [PATCH] microblaze: don't use copy_file_range syscall with kernel headers < 4.10 copy_file_range syscall was added for microblaze in 4.10. This patch makes the MicroBlaze kernel-features.h undefine __ASSUME_COPY_FILE_RANGE for toolchains built with kernel headers < 4.10. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_COPY_FILE_RANGE) [__LINUX_KERNEL_VERSION < 0x040A00]: Undef.
