Hi again,
before I sent my patches out I have done a lot of testing. Everything
seemed to work fine. But an aideupdate started by a cron-job revealed
that the patches even introduce two new bugs. At least I have never
hit these bugs before. There were no identical traces in the logfiles
of the last year.
Perhaps they are also to be found in 2.6.33-rc. I'll do more testing
and try it another time again.
Sincerely yours,
Marcus
