Re: AUFS incorrectly identifies files as directories.

 Marty Rosenberg:
 One user told me there is a conflict of symbol in aufs and in
 unionfs. Did you load or build unionfs into your kernel?
 :::
 I compiled aufs as a module, by modifying linux/fs/Kconfig, and
 whatnot.
 
 Although I am unsure, won't you try aufs with vanilla kernel, and without
 unionfs?
 
 And thank you very much for your offer. I will ask you something to test
 in the future. Currently I don't, except this (above) one.

 Sorry if I didn't say what I was using.  for the battery of tests I did, I 
used a vanilla kernel, and I dind't have the unionfs module compiled at all.  
It was the aufs module that was built by piggybacking into the kernel's make 
structure.

 BUG at /root/aufs.wcvs/aufs/fs/aufs/super.c:357!
 must be a bug in aufs. I will fix it as soon as possible.
 
 Please apply this patch, which is against the latest source in CVS.
 If you success, it will be included in next release.
 
 This patch is only for BUG at super.c:357 only.

I applied the patch, and it seems to have worked great. But I also tried 
reproducing the bug with the old source, and it doesn't seem to work. 
That is, I can't get a new BUG at super.c:357. I mount /storage, do a 
mount -o remount,udba=inotify /storage, and it seems to work. (NOTE: 
this is this weeks monday release, *not* the version I was running when 
I first stumbled upon BUG at super.c:357)

So either there were other conditions to cause my BUG @ super.c:357, or 
the newest CVS fixed the problem by itself.

In any case, thanks a lot. :-)

Kindest regards, Jørgen Tjernø.

There is a condition to reproduce this bug.

$ cd /your/aufs/subdir
$ sudo mount -o remount,udba=inotify /your/aufs
then you will meet BUG @ super.c:357 again.

It means the subdir is in use, and aufs tries some processing at
remount-time. If you didn't use any of subdir, you would not meet the
bug. I guess the samba service daemon refered a subdir when the first
time you met the bug.
