o news
- bugfix (fs/aufs25 only, currently): pin the hierarchy on lower branch
and new ignore scheme for inotify (still debugging).
under heavy i/o (including rename(2)), aufs may misunderstand
the child-parent relationship. new structure au_pin locks both parent-
child and verifies them.
additionally, when udba=inotify is specified, aufs sets inotify watch
internally for the parent (and grand parent) dir in cache, and ignores
the events triggered by aufs internal activity. this was done by
locking the lower dir and setting 0 to the event mask for the lower
dir, but it might ignore the event fired by other process, for example
write(2) to the lower file.
the new method stops setting 0 to the mask, and ignores the event made
by aufs only.
this fix is not backported to fs/aufs yet since it is still
debugging. so the old behaviour is taken on the older kernels.
people will call it crazy due to many locks.
