From: Darrick J. Wong <djwong@xxxxxxxxxx>
There are a number of fstests that employ special (and now unsupported)
XFS filesystem configurations to perform testing in a controlled
environment. The presence of the QA_CHECK_FS and MSGVERB variables are
used by mkfs.xfs to detect that it's running inside fstests, which
enables the unsupported configurations. Nobody else should be using
filesystems with tiny logs, non-redundant superblocks, or smaller than
the (new) minimum supported size.
