Log:
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.
