Mikulas Patocka 73dfd078cf dm snapshot: trigger exceptions in remaining snapshots during merge ... When there is one merging snapshot and other non-merging snapshots, snapshot_merge_process() must make exceptions in the non-merging snapshots. Use a sequence count to resolve the race between I/O to chunks that are about to be merged. The count increases each time an exception reallocation finishes. Use wait_event() to wait until the count changes.
