commit: 8594c345e77db3d0d9aafeb18e475212ce89e58d [2/3] Merge commit 'ad4d05329d' into work.statx
config: i386-randconfig-x072-201709 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        git checkout 8594c345e77db3d0d9aafeb18e475212ce89e58d
        # save the attached .config to linux build tree
        make ARCH=i386 

Note: the vfs/work.statx HEAD 2335fc954ccf342e854379df1f6e81c3a98cf489 builds fine.
      It only hurts bisectibility.

Yes, which is precisely why the pull request had been for rebased-statx and
not work.statx.  Alternative would be work.statx-minimal with even more
fixups in merge commit.  Identical resulting trees, so the testing in -next
applies to either variant, and rebased-statx has neither backmerges nor
fixups in merge...
