Subject: add an ordered_extent pointer to struct btrfs_bio v2
Date: Wed, 31 May 2023 09:53:53 +0200 [thread overview]
Message-ID: <20230531075410.480499-1-hch@lst.de> (raw)
Hi all,
this series adds a pointer to the ordered_extent to struct btrfs_bio to
reduce the repeated lookups in the rbtree. For non-buffered I/Os the
I/O will now never do a lookup of the ordered extent tree (other places
like waiting for I/O still do). For buffered I/O there is still a lookup
as the writepages code is structured in a way that makes it impossible
to just pass the ordered_extent down. With some of the work from Goldwyn
this should eventually become possible as well, though.
Changes since v1:
- rebased to the latest misc-next tree with the changes to not split
ordered extents for zoned writes
- rename is_data_bio to is_data_bbio
- add a new bbio_has_ordered_extent helper
