Subject: [PATCH 5/9] check: document mkfs.xfs reliance on fstests exports
Date: Tue, 28 Jun 2022 13:21:45 -0700	[thread overview]
Message-ID: <165644770574.1045534.3646229611370914936.stgit@magnolia> (raw)
In-Reply-To: <165644767753.1045534.18231838177395571946.stgit@magnolia>

From: Darrick J. Wong <djwong@kernel.org>

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.
