Currently btrfs raid56 uses btrfs_raid_bio::faila and failb to indicate which stripe(s) had IO errors. But that has some problems: - If one sector failed csum check, the whole stripe where the corruption is will be marked error. This can reduce the chance we do recover, like this: 0 4K 8K Data 1 |XX| | Data 2 | |XX| Parity | | | In above case, 0~4K in data 1 should be recovered using data 2 and parity, while 4K~8K in data 2 should be recovered using data 1 and parity. Currently if we trigger read on 0~4K of data 1, we will also recover 4K~8K of data 1 using corrupted data 2 and parity, causing wrong result in rbio cache. - Harder to expand for future M-N scheme As we're limited to just faila/b, two corruptions. - Harder to expand to handle extra csum errors This can be problematic if we start to do csum verification. This patch will introduce an extra @error_bitmap, where one bit represents error that happened for that sector. The choice to introduce a new error bitmap other than reusing sector_ptr, is to avoid extra search between rbio::stripe_sectors[] and rbio::bio_sectors[]. Since we can submit bio using sectors from both sectors, doing proper search on both array will more complex. Although the new bitmap will take extra memory, later we can remove things like @error and faila/b to save some memory. Currently the new error bitmap and failab mechanism coexists, the error bitmap is only updated at endio time and recover entrance.

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. Reviewed-by: NAnand Jain <anand.jain@oracle.com> Signed-off-by: NDavid Sterba <dsterba@suse.com>

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.
