[Samba] With streams_xattr enabled, ADS are written correctly but not retrieved

Hello,

I'm running Samba 3.6.6-1 on my x64 Arch Linux installation. I recently
decided to have my samba share support NTFS's Alternate Data Streams by
using streams_xattr or streams_depot. With streams_xattr I discovered that
if I copy a file having an ADS from a win7 box, on the linux console, I can
see the ADS as an xattr attached to the file. However when I copy the file
back to my win7 box using windows explorer, there are no ADS entries on it.
This is not true if I use streams_depot.

To this email, I've appended logs (log level=3) generated when I copy the
file back using windows explorer. I haven't been able to make much sense of
them or spot anything that's causing streams_xattr to not function
correctly.

On a side not, when I first enabled streams_xattr (true about streams_depot
too), I was getting an NT_STATUS_NETWORK_BUSY from smbd which was also
causing windows to report an 'unexpected error'. Upon some research I found
this: https://bugzilla.samba.org/show_bug.cgi?id=7537 . Upon disbaleing
kernel oplocks, this error was gone. I'm wondering if I could still have
the kernel oplocks on and there's another way to solve it, since that bug
is 2 years old.

thanks,
Puneet
