Reviewing the patch again, we no longer set the default gfpmask on the
inode to contain NORETRY and instead add the NORETRY at the one spot in
the code where we are trying to do a large allocation and our shrinker
would be prevented from running (due to contention on struct_mutex).

I do not know how this causes memory corruption across hibernate and would
appreciate any insights.
