Hello Carlo. The ranters! comment:
I can understand your way of looking at things. But you'd better be a bit more careful with statements like these below, if you don't really know what's going on. Just FYI: All possible traces - Ingo asked for - are on Ingos desk! My intention is to support you folks as good as I can to get the issues solved. As a user, with a rather limited knowledge about ck or cfs, I am just able to judge on the results these patches are delivering. I'll go always for the one - if I have a choice - matching my requirements! Since there is just one patch left in the near future, at least the way it looks to me today, I am trying of course to support Ingo the best I can to identify potential issues. Constructive critism - always welcome!
