Hi all,
This is the final regular release in this year. If something wrong
happens, I may release a fixed version as an emergency release.
Have nice holidays!

o bugfix
- bugfix(completed): stop recursive si lock, reported by Louis Rilling,
refine the readdir call from NFSD entirely.
+ temporary si unlock/lock in au_lkup_by_ino() and decode_by_path().
+ new function si_nfsd_read_lock().
+ rename struct au_decode to struct au_nfsd_si_lock.
+ in readdir(), unlock all except fi write-lock and call
lockdep_off/on().
+ stop checking si lock in au_fvdir_cache().
+ remove struct au_nfsd_readdir_pid.
+ remove struct au_nfsd_pid.
+ remove au_nfsd_do_read_lock(), au_nfsd_read_lock() and
di_nfsd_read_lock_parent().
+ remove si_nfsd_pid member.
+ remove si_nfsd_pid_{,un}reg() and au_nfsd_test_si_lock().
+ remove ii_nfsd_readdir member and au_nfsd_readdir_alloc().
+ remove au_nfsd_readdir_{alloc,free,reg,unreg,test}().
+ remove au_decode_{,un}lock().
+ remove si_hin_wq and si_nfsd_pid member.
+ remove au_hin_wq_{init,wake}().
+ support the hierarchy of pin3.
+ revert the big aufs lock.
- bugfix: mutex lock for the lower inode while updating the aufs inode
attributes.
o misc
- allow flushing no-wait-task even if the current process is NFSD.
- minor enhancement: for NFSD, convert -EBUSY into -ESTALE.
- make silly_{,un}lock() before linux-2.6.27 only. in linux-2.6.27 and
later, read-lock si and ii inconditionally.
- print the opened files too.
- remove the unused functions au_nfsd_lockdep_off/on().
