Hi,
I am resending this patch from Pete Zaitchev/Al Viro to remind that there is still an open issue with the ibm partition code. It works for us and if there isn't a better solution in sight I'd suggest to include it into 2.5.x. A better solution would be to make ioctls work on half-open block devices but I understand that this is complicated and takes time to implement. Anybody with a veto ?

blues skies,
Martin.
