Subject: [PATCH 3/9] xfs: test mkfs.xfs sizing of internal logs that
Date: Tue, 28 Jun 2022 13:21:34 -0700	[thread overview]
Message-ID: <165644769450.1045534.8663346508633304230.stgit@magnolia> (raw)
In-Reply-To: <165644767753.1045534.18231838177395571946.stgit@magnolia>

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

This is a regression test that exercises the mkfs.xfs code that creates
log sizes that are very close to the AG size when stripe units are in
play and/or when the log is forced to be in AG 0.

Signed-off-by: Darrick J. Wong <djwong@kernel.org>
