Comment 3 Steve Dickson 2017-11-10 16:11:08 UTC
Here is the reason loopback mounts will always
be acceptable to hangs:

1) nfsd wants memory. It tries to obtain this by flushing pagecache. 
2) The pagecache tries to free memory by flushing page cache allocated to files over nfs. 
3) nfs tries to flush paged by writing back to the nfs server. 
4) nfsd needs memory. go back to 1.
