Sorry about the delay - was out of town.

Ran some tests today with the three patch (remove writepage for
cifs.ko) series.  Let me know if any updates for those.  Also let me
know which gti branch you would like to see these merged from (mine or
yours e.g.)

I did see an intermittent  failure (when run with these three patches)
that doesn't appear to be obviously related to yours but am still
investigating it.   Test 043 failed once, and on one of retries of the
group  -  test 045 failed once. See example below.  This looks related
to an issue with deferred close (handle leases) and reference counts
holding up unmount, and not related to these patches (at least at
first glance).   Continuing to debug
