2009-04-02	dm raid1: add is_remote_recovering hook for clusters	Jonathan Brassow	1	-0/+10
	The logging API needs an extra function to make cluster mirroring possible. This new function allows us to check whether a mirror region is being recovered on another machine in the cluster. This helps us prevent simultaneous recovery I/O and process I/O to the same locations on disk. Cluster-aware log modules will implement this function. Single machine log modules will not. So, there is no performance penalty for single machine mirrors.

2009-04-02	dm log: remove struct dm_dirty_log_internal	Mike Snitzer	1	-0/+3
	Remove the 'dm_dirty_log_internal' structure. The resulting cleanup eliminates extra memory allocations. Therefore exposing the internal list_head to the external 'dm_dirty_log_type' structure is a worthwhile compromise.
