o bugfix
- bugfix: increment sbinfo generation in cases of br_mod() for sensing
whiteout, xino/noxino and udba=inotify, too. introducing
au_is_whable() and sbr_is_whable(). call au_sigen_inc() from
do_opts(), reported by Jorgen P. Tjerno.
o news
- support sysfs and NFS-exporting, introducing sysaufs.c,
CONFIG_AUFS_SYSAUFS, export.c, CONFIG_AUFS_EXPORT and a new module
parameter 'brs.'
- remove AUFS_DEBUG_RWSEM.
- workaround an application bug when 'dlgt' is specified.
generally, read(2) or write(2) may return the value shorter
than requested. But many applications don't support it,
for example bash.
- support file gid when 'dlgt' is set.
o misc
- add a note about SMP.
- add a note about lockdep, still testing.
- add a note about performance test.
- convert branch permission bits into an integer.
- add an branch mode alias 'rowh' which is equivalent to 'ro+wh.'
- macro functions are converted to inline function.
- rename some symbols.
- merge hidden_notify_change() into vfsub_notify_change().
- convert the type of aufs_nwkq to short, since linux/kernel/params.c
prints as '%c' for 'byte'.
- accounting in workqueue, refine the algorithm of choosing the thread.
- refined LHASH_PATCH and DLGT condition for lkup_one() and lkup_hash().
- refine file read/write when 'dlgt' is specified.
- refine DLGT condition for minor optimization.
- stop setting the first branch mode to 'rw' by default, when the mount
flag is 'ro.'
