Jiaying Zhang 744692dc05 ext4: use ext4_get_block_write in buffer write ... Allocate uninitialized extent before ext4 buffer write and convert the extent to initialized after io completes. The purpose is to make sure an extent can only be marked initialized after it has been written with new data so we can safely drop the i_mutex lock in ext4 DIO read without exposing stale data. This helps to improve multi-thread DIO read performance on high-speed disks. Skip the nobh and data=journal mount cases to make things simple for now.
