r17125: Drastic problems require drastic solutions. There's
no way to get all the cases where kernel oplocks are on and we can't open the file and get the correct semantics (think about the open with truncate with an attribute only open - we'd need a vfs change to add the truncate(fname, len) call). So always drop the share mode lock before doing any real fd opens and then re-acquire it afterwards. We're already dealing with the race in the create case, and we deal with any other races in the same way. Volker, please examine *carefully* :-). This should fix the problems people reported with kernel oplocks being on. Jeremy. (This used to be commit 8171c4c404e9f382880c65daa0232f89e560f399)
