btrfs: make btrfs_add_ordered_extent_dio take btrfs_inode

2020-07-27T10:55:34+00:00

Simply forwards its argument so let's get rid of one extra BTRFS_I by
taking btrfs_inode directly.

already takes btrfs_inode.

btrfs: remove no longer used trans_list member of struct btrfs_ordered_extent

2020-07-27T10:55:25+00:00

The 'trans_list' member of an ordered extent was used to keep track of the
ordered extents for which a transaction commit had to wait. These were
ordered extents that were started and logged by an fsync. However we don't
do that anymore and before we stopped doing it we changed the approach to
wait for the ordered extents in commit 161c3549b45aee ("Btrfs: change how
we wait for pending ordered extents"), which stopped using that list and
therefore the 'trans_list' member is not used anymore since that commit.
So just remove it since it's doing nothing and making each ordered extent
structure waste memory (2 pointers).

btrfs: remove no longer used log_list member of struct btrfs_ordered_extent

2020-07-27T10:55:25+00:00

The 'log_list' member of an ordered extent was used keep track of which
ordered extents we needed to wait after logging metadata, but is not used
anymore since commit 5636cf7d6dc86f ("btrfs: remove the logged extents
infrastructure"), as we now always wait on ordered extent completion
before logging metadata. So just remove it since it's doing nothing and
making each ordered extent structure waste more memory (2 pointers).
