hi all,

make check with the new version of glibc has two new failures on my custom
system:

 FAIL: misc/tst-mount-consts

From misc/tst-mount-consts.out:

 test.c:2:10: fatal error: linux/mount.h: No such file or directory
  #include <linux/mount.h>

/usr/include/linux/mount.h is indeed missing and I checked that 
make headers_install with my current kernel would not change that.

 FAIL: nptl/tst-pthread-gdb-attach-static

I have attached the file nptl/tst-pthread-gdb-attach-static.out.

Should I worry about those new failed tests?

Here is some data about my setup:

-glibc configure options:
 --prefix=/usr --enable-kernel=4.9.0 --host=x86_64-pc-linux-gnu --disable-experimental-malloc
-kernel version: 4.9.320
-installed kernel headers: from some older 4.9.x kernel
-gcc version: 7.5.0
-gdb version 9.1

Regards,

Michael Brunnbauer
