Test out some issues we have at the moment dealing with writing when out of space

#! /bin/sh
# XFS QA Test No. 083
#
# Exercise filesystem full behaviour - run numerous fsstress
# processes in write mode on a small filesystem.  NB: delayed
# allocate flushing is quite deadlock prone at the filesystem
# full boundary due to the fact that we will retry allocation
# several times after flushing, before giving back ENOSPC.
