commit 98eb11ef99418e690ae43116432c0566a28da8a0
Author: Tim Prouty <tprouty at samba.org>
Date: Thu Jan 8 17:21:08 2009 -0800
s3: Remove a few unnecessary checks from the streams depot module and fix to work with NTRENAME
Handling of error codes when renaming a file to a stream and a stream
to a file is now done in rename_internals_fsp.
The NTRENAME stream path only passes in the stream name, so the new
base can now be different from the old base.

s3: Remove a few unnecessary checks from the streams xattr module
Handling of error codes when renaming a file to a stream and a stream
to a file is now done in rename_internals_fsp.
The NTRENAME stream path only passes in the stream name, so the new
base can now be different from the old base.
commit fb888dd4f10b00edb258e965ea06e29fa76827d6

s3: Allow renames of streams via NTRENAME and fix stream error codes on rename
The test_streams_rename2 test in RAW-STREAMS verifies these changes
