So, to be clear, this patch solves the XFS deadlock using a different 
approach (to the now reverted integrity_read approach), which Christoph 
also says is more correct generally.  Correct?

No.  It is in addition to the previous patches - the patches were
correct for the IMA interaction with the I/O path.  It just turns
out that the function was also reused for reading certificates
at initialization time, for which that change was incorrect.

If this series is applied first the integrity_read code is not
used for that path any more.

Ok.  Sorry I hadn't looked at the code in detail at this stage during the 
conference and wanting to just revert back to something that Linus can 
safely pull before the merge window closes.
