...ther point in the transaction op vector to do some cleanup and/or an explicit WEDGE op to accomplish the same thing?) - This still uses the existing ioctl start transaction call. Depending on how Josef''s ENOSPC journal_info stuff works out, I should be able to avoid the current global open_ioctl_trans counter for a cleaner interaction with the btrfs transaction code. - The data space reservation is still missing. I need a way to find which space_info will be used, and pin it for the duration of the entire transaction. - The metadata reservation is a worst case bound. It could be less con...
