Log Message:
CFS (#ifdef CFS_CHARD_SYNC_FIX):
- Fix bug introduced in CVS tag OPENSSI-FC-1-9-6-PRE13. Writer can get stuck in cfs_wait_on_requests() during failover. When cfs_prepare_reflush() is traversed the requests marked for commit are re-dirtied and locked. However locked requests cannot be flushed. So cfs_wait_on_requests() waits forever for the dirtied requests to get flushed.
