The fix we want is to replace that line with
   struct wait_bit_queue_entry wait;
I should have checked more carefully - sorry.

I guess we wait for rc3?

Kent: could you please make that change?  The inode_bit_waitqueue() does
initialisation equivalent of DEFINE_WAIT_BIT() so you only need the declaration.

Thanks,
