USE_BIG_LOOPFS is really misnamed - it can be used on real devices just as easily as loop devices. It really means we are testing a large scratch device and that we should enable the special filesystem filling and checking options that enable xfstests to be run sanely on large XFS filesystems.

# 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
