Hi all,

This my third trial to post entire aufs2 source files for reviewing
(#3 and #4 were partial).
Kindly Greg KH reviewed them and gave me an advice to send full files.
These patches are aginst 2.6.30-rc1.

Here are changes since the post #2.
- bugfix: stop storing nd->intent.open.flags when the file is not a
regular file
- convert some aufs entries from sysfs to debugfs
- support ramfs branch
- stop changing ->f_flags at modifying a branch permission
- stop copying-up in mmap(2) when MAP_PRIVATE is specified
- simplify, ->f_op is always set
- follow the changes in mainline
+ make file_operations const
+ acquire ->f_lock at touching ->f_flags
+ support credential and IMA at opening a file
+ support fmode_t
+ support relatime, ignore silently (temporary workaround)
- several fixes in documents.

In public aufs2 GIT tree, I made more enhancements which are NOT
included here. Because it is better to keep files smaller for reviewing
on LKML.
The dropped features are,
- VDIR variable size
- support exporting via NFS

Thnak you for reviewing.
And please consider merging aufs2.
