Hi, Okajima-san,
Thanks a lot for looking into this.
After applying your patch, I got EINTR like this:
 aufs do_xino_fwrite:85:java[1077]: err -4
 aufs au_xino_do_write:439:java[1077]: I/O Error, write failed (-4)
The patch actually worked as an ad-hoc solution for the bug, as it breaks
the loop in do_xino_fwrite(). (it is not a mutex deadlock! sorry for the
misunderstanding.)

I'll continue to find the source of this EINTR loop.
Maybe this is a bug of Linux kernel itself (kernel/pid_namespace.c?) rather
than AUFS, but I'm still not sure.

Thanks for reporting. This is new to me and ML.
Here is a debug patch. Please apply, reproduce and post the [4]kern.info
log.
Note that the patch never solves the problem. This is just to
investigate the problem.
