Here are some comments: - I think that you can use kernel threads for map_worker since dmu_map says that we might reorder I/Os. - What is the purpose of dmu_request->deps? I guess that it is for preventing I/O being reordered. if so, again, you don't need to do that. - Would be better to move non-transport functions (map_worker, copy_block, etc) to dm-userspace.c? - How does the current kernel/user interface support multiple destination feature? - Needs some cosmetic fixes (removing needless whitespaces and braces, etc) -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
