Hello Okajima-san, Until aufs4.10, the kernel compilation on arm architecture was successful as well as x86 architecture, and the aufs worked with no problem.
However, aufs4.11.7+ fails to compile the kernel on arm architecture. Note, the kernel compilation with aufs4.11.7+ on x86 architecture works with no problem. Step to reproduce the problem: $ wget -q https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.11.12.tar.xz $ tar xpJf linux-4.11.12.tar.xz $ git clone https://github.com/sfjro/aufs4-standalone.git $ ( cd aufs4-standalone ; git checkout origin/aufs4.11.7+ ; git reset --hard 71715aa ) $ cd linux-4.11.12 $ patch -Np1 -i ../aufs4-standalone/aufs4-kbuild.patch $ patch -Np1 -i ../aufs4-standalone/aufs4-base.patch $ patch -Np1 -i ../aufs4-standalone/aufs4-mmap.patch $ patch -Np1 -i ../aufs4-standalone/aufs4-standalone.patch $ cp -av ../aufs4-standalone/Documentation . $ cp -av ../aufs4-standalone/fs . $ cp -pv ../aufs4-standalone/include/uapi/linux/aufs_type.h include/uapi/linux $ make defconfig $ make menuconfig (CONFIG_AUFS_FS=m) $ make (snip) LD fs/aufs/built-in.o CC [M] fs/aufs/module.o In file included from fs/aufs/aufs.h:44:0, from fs/aufs/module.c:24: fs/aufs/file.h: In function 'au_do_vm_file_reset': fs/aufs/file.h:286:9: error: dereferencing pointer to incomplete type f = vma->vm_file; ^ fs/aufs/file.h:288:5: error: dereferencing pointer to incomplete type vma->vm_file = file; ^ fs/aufs/file.h: In function 'au_vm_prfile_set': fs/aufs/file.h:322:5: error: dereferencing pointer to incomplete type vma->vm_prfile = file; ^ scripts/Makefile.build:294: recipe for target 'fs/aufs/module.o' failed make[2]: *** [fs/aufs/module.o] Error 1 scripts/Makefile.build:553: recipe for target 'fs/aufs' failed make[1]: *** [fs/aufs] Error 2 Makefile:1002: recipe for target 'fs' failed make: *** [fs] Error 2 Thanks in advance.
