Subject: [PATCH 05/11] xfs: remove flags argument from xfs_inode_ag_walk
Date: Tue, 19 May 2020 18:45:49 -0700	[thread overview]
Message-ID: <158993914950.976105.8586367797907212993.stgit@magnolia> (raw)
In-Reply-To: <158993911808.976105.13679179790848338795.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.
