This bug is a follow up from subversion issue:
The scenario involves a Linux (svn) client contacting a remote Windows server. The svn repository is saved on an NTFS file-system.
running the lock/unlock test code, we see that it is possible to lock a file, but we get an error when trying to unlock it.
see attached files there and here.

Basic file locking test
This seems to work properly on recent kernel versions. Tested on win2k8 server serving out NTFS filesystem. Kernel version was 2.6.31-0.94.rc4.fc12.x86_64.
I'm going to close this as FIXED though I'm not exactly clear on which patch actually fixed it. If you find that it's not working, please reopen the bug.
