Creating an exception store API should make it easier to create new exception stores. Once completed, a simple exception store module should be all that is needed. These patches are preliminary. There is still work to do, but I'm offering this time as an opportunity to complain about the general direction. Basically, things compile but that is all I've tested. If it's ok with everyone, I'd also rather have 'dm_exception_store*' structure names changed to 'dm_exstore*' for brevity. However, I used the longer names because I thought it would be the more likely choice. Fujita Tomonori, the API change should prove exceptionally useful to you... and I don't think you will need the 'message' interface to create your exception stores anymore. You should be able to use more standard methods. brassow -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
