o current problems
- isolated inode survived deleting a branch (done).
- hang at reboot/shutdown (it may not be an aufs problem) (tried fixing).
- setting inode number which was previously assigned ("broken ino"
msg) (testing).
- getdents(2) returns nothing. this may involve two problems.
- cpup_wh_file() failure.
o bugfix
- bugfix: use SMP-safe atomic_{inc,dec}_return().
- bugfix: memory barrier after atomic_set().
- bugfix: make lower dir opaque even if it is emptry, to keep xino consistency.
o news
- introduce external inode number bitmap.
+ remove backward compatibility atomic_long.
+ rename xino_init() to xino_br().
+ move br_xino_{read,write} to si_x{read,write}.
+ check the unlinked but remaining pseudo-link.
+ leave xino for the remove file/dir, instead clear them in iinfo.
+ maintain inode attributes and xino for the rename-target and the
lower rename-source.
+ maintain xino for the removed file.
+ new options 'trunc_xib' and 'notrunc_xib'
+ truncate the xino bitmap at deleting a branch by default.
+ show the bitmap file size in sysfs.
+ free the bitmap buffer at unmouting.
- refine hinotify.
+ wait for the completion of 'notified' tasks at revalidating.
+ wait for the completion of 'notified' tasks at lookup.
+ re-construct internal functions.
+ support clearing xino
+ maintain digen recursively when a dir was renamed
+ introduce wait-able 'nowait' task.
+ stop unnecessary write to xino.
+ support for whiteouts.
+ stop unnecessary digen in IN_MOVE_SELF.
+ leave digen for the renamed dir.
+ modify the 'broken ino' msg to reflect the problem correctly.
- describe about the inode number of the directly renamed dir and its
warning, which was called incorrectly as 'broken ino' msg.
o misc
- describe about the compilation on a distribution (or customized)
kernel.
- I forgot to mention about /etc/default/auplink
- rename 'changable' to 'changeable.'
- warn about aufs specific EXDEV error.
- define rw_{read,write}_trylock().
- rename 'au_xxx_opts()' to 'au_opts_xxx().'
- warn inotify without xino.
- move need_dlgt() from vfsub.h to to super.h.
- temporary support for imod option.
- introduce rt-compat.patch.
