Subject: [PATCH 05/11] xfs: remove flags argument from xfs_inode_ag_walk
Date: Tue, 31 Dec 2019 17:06:30 -0800 [thread overview]
Message-ID: <157784079074.1360343.14648160580278893006.stgit@magnolia> (raw)
In-Reply-To: <157784075463.1360343.1278255546758019580.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
The incore inode walk code passes a flags argument and a pointer from
the xfs_inode_ag_iterator caller all the way to the iteration function.
We can reduce the function complexity by passing flags through the
private pointer.
