commit a85cbe6159ffc973e5702f70a3bd5185f8f3c38d upstream. and include <linux/const.h> in UAPI headers instead of <linux/kernel.h>. The reason is to avoid indirect <linux/sysinfo.h> include when using some network headers: <linux/netlink.h> or others -> <linux/kernel.h> -> <linux/sysinfo.h>. This indirect include causes on MUSL redefinition of struct sysinfo when included both <sys/sysinfo.h> and some of UAPI headers: In file included from x86_64-buildroot-linux-musl/sysroot/usr/include/linux/kernel.h:5, from x86_64-buildroot-linux-musl/sysroot/usr/include/linux/netlink.h:5, from ../include/tst_netlink.h:14, from tst_crypto.c:13: x86_64-buildroot-linux-musl/sysroot/usr/include/linux/sysinfo.h:8:8: error: redefinition of `struct sysinfo' struct sysinfo { ^~~~~~~ In file included from ../include/tst_safe_macros.h:15, from ../include/tst_test.h:93, from tst_crypto.c:11: x86_64-buildroot-linux-musl/sysroot/usr/include/sys/sysinfo.h:10:8: note: originally defined here Link: https://lkml.kernel.org/r/20201015190013.8901-1-petr.vorel@gmail.com Signed-off-by: Petr Vorel <petr.vorel@gmail.com> Suggested-by: Rich Felker <dalias@aerifal.cx> Acked-by: Rich Felker <dalias@libc.org> Cc: Peter Korsgaard <peter@korsgaard.com> Cc: Baruch Siach <baruch@tkos.co.il> Cc: Florian Weimer <fweimer@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
