[Unionfs] Unionfs Patch Problem

[Ngo, Andrew]

Hi,

The patching of unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz needs various
files (fs/stack.c, include/linux/fs_stack.h), and directory
(fs/unionfs).  So I did not proceed with this route.  The
unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz, however, generates good
patch files (drivers/md/dm-mpath.h, fs/Makefile, and
include/linux/namei.h).  I copied these files generated/patched from
unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz

Now, I am patching the RHEL5 kernel 2.6.18.8.el5 with the original
unionfs-2.3.3_for_2.6.18.8.diff.gz, and then overlay the above three
files saved from patching with the
unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz.  

The compile operation went further, but eventually it failed (See
attached make.out1 file).

  CC [M]  fs/unionfs/rdstate.o
  CC [M]  fs/unionfs/copyup.o
fs/unionfs/copyup.c: In function 'copyup_xattrs':
fs/unionfs/copyup.c:38: error: implicit declaration of function
'vfs_listxattr'
make[2]: *** [fs/unionfs/copyup.o] Error 1
make[1]: *** [fs/unionfs] Error 2
make: *** [fs] Error 2

Does anyone know how to fix this compile problem???  Thanks in advance.

Andy Ngo

Thanks Fernado,

The unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz really help!  All the
patching problems that I encountered on my previous message are gone.
Now I am running into a compile problem.  Here is how I get here:

1.  Patched my rhel5 (kernel 2.6.18.8.el5) with the
unionfs-2.3.3_for_2.6.18.8.centos5.diff.gz
2.  make menuconfig and set unionfs to M and the two suboptions (unionfs
extended attributes and debug unionfs) to enabled 3.  make

The make command failed with the following error:
  .......
  CC      fs/splice.o
  CC      fs/sync.o
make[1]: *** No rule to make target `fs/stack.o', needed by
`fs/built-in.o'.  Stop.
make: *** [fs] Error 2

Hi,

 Try this diff instead the orig.
