18 mrt 1995: 0.24 Working background read-ahead. (still problems)
26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2).
Statistics implemented, though separate stats206.h.
- Accessible trough ioctl 0x1000 (just a number).
+ Accessible through ioctl 0x1000 (just a number).
Hard to choose between v1.2 development and 1.1.75.
Bottom-half doesn't work with 1.2...
0.25a: fixed... typo. Still problems...
