The stop aborts the processing of the previous start by setting the RECOVERY_STOP flag. dlm_recoverd is erroneously clearing this flag and ignoring the stop/abort if it happens to take up the start after the stop meant to abort it. The fix is to check the sequence number that's incremented for each stop/start before clearing the flag. Signed-off-by: David Teigland Signed-off-by: Steven Whitehouse --- Reading git-diff-tree failed
