o bugfix
- bugfix: restore lockdef_off/on(), a regression on 20080922.
- bugfix: check if the destroying inode is dead when maintaining the
inode generation.
- bugfix: when the inode/dentry was still cached, check its generation.
o news
- support mnt_want/drop_write() in linux-2.6.26 and later.
+ introduce the bit flags and the branch index to struct au_pin, and
change the parameter for au_pin functions.
+ introduce the bit flag for crazy locks for rename(2).
+ new inlined functions au_br_want/drop_write().
+ new abstract functions au_mnt_want/drop_write().
+ convert the parameter 'dentry' for clean_wh(), au_whdir_clean() and
au_whdir(), into 'path.'
+ convert the parameter 'nfsmnt' of au_wh_init() into 'h_mnt.'
- add a note about openvz and sysrq, reported by Mitsuru SHIMAMURA.
- add a note about the size of xigen file.
o misc
- minor optimization: skip the actual xib truncation when the file size
is small enough.
- convert si_xigen_lock and si_xigen_next into a single atomic_t.
- always downgrade iinfo rw_sem too.
- use struct au_spl instead of spinlock + list.
- new tiny functions au_spl_add/del().
- call au_spl_add/del() instead of spin_lock/unlock() + list_add/del().
- (fs/aufs only) convert mntput() + dput() into path_release().
- (fs/aufs only) move free_sbinfo() from super.c to sbinfo.c as
au_si_free().
- (fs/aufs only) move alloc_sbinfo() from super.c to sbinfo.c as
au_si_alloc().
- rename sysaufs_sbi_init() to sysaufs_si_init().
