Kirill,

You should be as rude as you can if you send an email to lkml! You
are breaking the well-known rules, and now I have to mimic your wrong
behaviour.

Come on. You have found the nontrivial problem. This is much more
important than a simple fix.

And if we prefer a less-trivial fix which plays with ->curr recheck,
then it will be based on your idea, not mine.

So please make a patch after we know what Peter thinks.

Oleg.
