Can we > sort that out please? I did some testing to check that vmalloc is OK. First, boot and do a kernel build on COWed devices, which uses vmalloc space for the block bitmaps. Second, modprobed all modules, and made sure that one of them actually worked. Ran a kernel build to induce lots of context switches, made sure it still worked. It sure seems OK to me. Jeff
