Hi,=0A=
=0A=
I've just attempted to build a powerpc kernel from 4.11-rc2 using a =0A=
custom defconfig (available on request) and I'm hitting the following =0A=
error in the early stages of compilation.=0A=
=0A=
<stdin>:1325:2: error: #warning syscall statx not implemented [-Werror=3Dcp=
p]=0A=
=0A=
Same thing seems to happen with mpc85xx_basic_defconfig.=0A=
=0A=
I don't actually need this syscall so I'd be happy to turn something off =
=0A=
to get things building. I did a quick search and couldn't see anything =0A=
on linuxppc-dev but google keeps correcting "statx" to "stats" so I =0A=
could have missed it.=0A=

The upstream commit
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a528d35e8bfcc521d7cb70aaf03e1bd296c8493f)
that introduces the statx syscall provides a test program. I will wire-up the
syscall on ppc64, run that test program and post the patch if the test program
works well.

Thanks, I'd be happy to test a patch here.=0A=

In the meantime I worked around the build issue by adding __INGORE_statx =

Is it actually breaking the build? It's meant to be a warning, and
that's all I get.

It breaks my builds for ppc and arm. We do have KCFLAGS=3D-Werror in our =
=0A=
environment but KCPPFLAGS=3D is not set so I'm not sure why it's stopping =
=0A=
compilation.=0A=

OK, I guess that must be it.
We turn on -Werror for all of arch/powerpc by default (unless
CONFIG_PPC_DISABLE_WERROR=y), but the syscall checking script is not
under arch/powerpc so shouldn't be affected by that.
