1207 does. It actually sends the STATUS_PENDING
1208 message followed by the STATUS_SHARING_VIOLATION
1209 message. Surely this means that all open
1210 calls (even on directories) will potentially
1211 fail in a chain.... ? And I've seen directory
1212 opens as the start of a chain. JRA.
1214 Update: 19th May 2010. Talking with Microsoft
1215 engineers at the plugfest this is a bug in
1216 Windows. Re-enable this code.
1219 * More subtlety. To match W2K8R2 don't
1220 * send a "gone async" message if it's simply
1221 * a STATUS_SHARING_VIOLATION (short) wait, not
1222 * an oplock break wait. We do this by prematurely
1223 * setting smb2req->async flag.
