[Unionfs] unionfs on RHEL5

[Erez Zadok]

Dave,

Take a look at these two files:

<http://download.filesystems.org/unionfs/stable/unionfs-2.4_for_2.6.18-RHEL5.diff.gz>
<http://download.filesystems.org/unionfs/stable/unionfs-2.3.3_for_2.6.18-RHEL5.diff.gz>

I ported both unionfs-2.3.3 and unionfs-2.4 to the rhel5 src tarball you
gave me.  Basically the main patch conflicts had to do with files in
drivers/md/*.[hc] which refer to "struct path" -- all instances of "struct
path" in those drivers/md files, have to be changed to "struct dm_path" to
avoid conflicts with a VFS-level new "struct path" definition

I cleanly built that kernel, but didn't test it yet.

Cheers,
Erez.
