Yeah, the preempt patch seems to have some rather nasty rejects against |
| 2 |
-aa's rather large (?!?!) patch set. I myself am either sticking |
| 3 |
2.4.17-r4 or building my own because I depend on preempt and refuse to |
| 4 |
use any kernel for my workstation without it. And the fact -aa's patch |
| 5 |
is huge and tested by a smaller audience then even -ac's patch set |
| 6 |
doesn't sit well with me either. |

Anyone know if some kind soul is maintaining a preempt + tested XFS |
| 9 |
patch? With the dozens of different kernel trees these days someone has |
| 10 |
to be doing something like that :) |
