Mad Hatter testifies - the small bio-s joining in
Originally written by
- Each I/O may have been split into several smaller I/O requests.
- This could have been because the original I/O was too big, or
due to being split across several devices (software-RAID, LVM), etc.
- Each small I/O that returns - has a status.
- The status of the original I/O will be "success" - only if all the
underlying I/O requests succeeded.
- Hopefully, the testimony accuracy is better than that of the Mad Hatter...
