Subject: [PATCH 05/18] xfs_scrub: remove moveon from spacemap
Date: Tue, 22 Oct 2019 11:50:56 -0700 [thread overview]
Message-ID: <157177025678.1461658.2280238130703744148.stgit@magnolia> (raw)
In-Reply-To: <157177022106.1461658.18024534947316119946.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Replace the moveon returns in the space map iteration code with a direct
integer return.
