Cannot partition 32GB disk on a 32bit machine

2014-06-19 Thread Alan Cox
The block code has 32bit cleanness problems with the iterator. This prevents things like partitioning a 32GB volume on a 32bit system. I hit this with a volume of exactly 32GB in size (easy to duplicate with virtual machines). Tracing at step by step through the kernel I found the problem lines
