commit: 335331bef622bd232800d50c85b54056fa02d808 [37/44] create_pipe_files(): switch the first allocation to alloc_file_pseudo()
config: i386-tinyconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
        git checkout 335331bef622bd232800d50c85b54056fa02d808
        # save the attached .config to linux build tree
        make ARCH=i386 

Note: the vfs/work.open3 HEAD c94be0673577f7373cf67bba317cef2db9094530 builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
