Subject: [PATCH 03/25] xfs: use ->t_firstblock in dir ops
Date: Tue, 3 Jul 2018 13:22:57 -0400 [thread overview]
Message-ID: <20180703172319.24509-4-bfoster@redhat.com> (raw)
In-Reply-To: <20180703172319.24509-1-bfoster@redhat.com>
Callers of the xfs_dir_*() functions currently pass an on-stack
firstblock variable. While the dirops infrastructure carries a
pointer to this variable, it never rolls the transaction and so it
is safe to use ->t_firstblock instead.
Fix up the various xfs_dir_*() callers to use ->t_firstblock. Also
remove the unnecessary parameter for xfs_cross_rename().
