Subject: [PATCH 09/11] xfs: turn dfp_done into a xfs_log_item
Date: Wed, 29 Apr 2020 17:05:09 +0200 [thread overview]
Message-ID: <20200429150511.2191150-10-hch@lst.de> (raw)
In-Reply-To: <20200429150511.2191150-1-hch@lst.de>
All defer op instance place their own extension of the log item into
the dfp_done field. Replace that with a xfs_log_item to improve type
safety and make the code easier to follow.
Also use the opportunity to improve the ->finish_item calling conventions
to place the done log item as the higher level structure before the
list_entry used for the individual items.
