[PATCH 06/10] xfs: test quota softlimit warning functionality

Darrick J. Wong
2021-03-09T04:41:14Z

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

Make sure that quota softlimits work, which is to say that one can
exceed the softlimit up to warnlimit times before it starts enforcing
that.

+# Check that quota softlimit warnings work the way they should. This means
+# that we can disobey the softlimit up to warnlimit times before it turns into
+# hard(er) enforcement. This is a functional test for quota warnings, but
+# since the functionality has been broken for decades, this is also a
+# regression test for commit 4b8628d57b72 ("xfs: actually bump warning counts
+# when we send warnings").
