Subject: Re: [PATCH] fs/ceph/addr: pass using_pgpriv2=false to fscache_write_to_cache()

For the moment, ceph has to continue using PG_private_2.  It doesn't use
netfs_writepages().  I have mostly complete patches to fix that, but they got
popped onto the back burner for a bit.

I've finally managed to get cephfs set up and can now reproduce the hang
you're seeing.
