The node sending the lock needs to resend if this happens. - A sends a master lookup for resource R to C - B sends a master lookup for resource R to C - C receives A's lookup, assigns A to be master of R and sends a reply back to A - C receives B's lookup and sends a reply back to B saying that A is the master - B receives lookup reply from C and sends its lock for R to A - A receives lock from B, doesn't think it's the master of R and sends an error back to B - A receives lookup reply from C and becomes master of R - B gets error back from A and resends its lock back to A (this resending is what this patch does) - A receives lock from B, it now sees it's the master of R and takes the lock Signed-off-by: David Teigland Signed-off-by: Steven Whitehouse --- Reading git-diff-tree failed
