# FS 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.
#
# Note that this test will intentionally cause console msgs of form:
# dksc0d1s4: Process [fsstress] ran out of disk space
# dksc0d1s4: Process [fsstress] ran out of disk space
# dksc0d1s4: Process [fsstress] ran out of disk space
