Subject: [PATCH 1/8] xfs_db: add a bmbt inflation command
Date: Wed, 17 Apr 2024 14:44:44 -0700 [thread overview]
Message-ID: <171338845795.1856674.18346350417816337879.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <171338845773.1856674.2763970395218819820.stgit@frogsfrogsfrogs>
From: Darrick J. Wong <djwong@kernel.org>
Add a command to xfs_db to clone a data fork mapping over and over
again. This will make it easier to exercise really high sharing counts.
