From afff169e1a16795e6d150536ac146481f39d9e82 Mon Sep 17 00:00:00 2001 From: Arnd Hannemann Date: Sat, 5 Sep 2015 01:06:18 +0200 Subject: [PATCH] btrfs-progs: makefile: drop u option from ar invocation In newer distros (ubuntu 15.10, fedora rawhide) the binutils ar uses the new D flag per default to build deterministic binaries. Without this patch the following warning is issued, when building btrfs-progs: [AR] libbtrfs.a /usr/bin/ar: `u' modifier ignored since `D' is the default (see `U') For libtrfs.a performance benefit of the u option can be neglected, so drop the u option and silence the warning. In the future one might want to explicitly add the D option anyway.
