[PATCH 00/40] Parameter and type changes to btrfs_inode

Many patches but also quite short, switching struct inode to struct
btrfs_node for structures and related functions in the io path, removing
some indirect function calls and typedefs.

[PATCH 01/40] btrfs: change how repair action is passed to btrfs_repair_one_sector

[David Sterba]

There's a function pointer passed to btrfs_repair_one_sector that will
submit the right bio for repair. However there are only two callbacks,
for buffered and for direct IO. This can be simplified to a bool-based
switch and call either function, indirect calls in this case is an
unnecessary abstraction. This allows to remove the submit_bio_hook_t
typedef.

[PATCH 02/40] btrfs: drop parameter compression_type from btrfs_submit_dio_repair_bio

[David Sterba]

Compression and direct io don't work together so the compression
parameter can be dropped after previous patch that changed the call
to direct.

[PATCH 03/40] btrfs: change how submit bio callback is passed to btrfs_wq_submit_bio

[David Sterba]

There's a callback function parameter for btrfs_wq_submit_bio that can
be one of: metadata, buffered data, direct io data. The callback
abstraction is unnecessary as we have all functions available.

Replace the parameter with a command that leads to a direct call in
run_one_async_start. The called functions can be then simplified and we
can also remove the extent_submit_bio_start_t typedef.

[PATCH 04/40] btrfs: simplify btree_submit_bio_start and btrfs_submit_bio_start parameters

[David Sterba]

After previous patches the unused parameters can be removed from
btree_submit_bio_start and btrfs_submit_bio_start as they don't need to
conform to the extent_submit_bio_start_t typedef.

[PATCH 27/40] btrfs: switch extent_io_tree::private_data to btrfs_inode and rename

[David Sterba]

The extent_io_tree::private_data was meant to be a preparatory work for
the metadata inode rework but that never materialized. Now it's used
only for an inode so it's better to change the appropriate type and
rename it.

  Remove the semicolon at the end of the function declaration.

Right, thanks. It gets removed in the next patch so the whole series
compiles, I don't think it needs to be resent.

  Yes, of course, no resend is required. I am fine.

  With patch 04/40 fixed.

  Reviewed-by: Anand Jain <anand.jain@oracle.com>

  For the series.

  Just a note, the naming convention for the local variables... as inode
  represents struct btrfs_inode, we shouldn't use the same name for
  struct inode. Instead, vfs_inode is better. And binode is gone.

Thanks, Anand

Yeah the naming could be done like that. Some functions interact only
with inode so I won't mind using that name but in case there are both it
would be better to use the vfs_ prefix.
