In the end, I think it's better to require stacking drivers to not use separate mempools other than bioset. Timer or not, using multiple alloc pools is brittle. Any path which ends up allocating in different orders for whatever reason can lead to subtle deadlock scenarios which can be very difficult to track down and, at least currently, there's no way to automatically detect them. Besides, w/ front-pad, it really shouldn't be necessary. Thanks. -- tejun -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
