These files were getting <linux/module.h> via an implicit include path, but we want to crush those out of existence since they cost time during compiles of processing thousands of lines of headers for no reason. Give them the lightweight header that just contains the EXPORT_SYMBOL infrastructure. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
Patch adds function o2net_fill_node_map() to return the bitmap of nodes that it is connected to. This bitmap is also accessible by the user via the debugfs file, /sys/kernel/debug/o2net/connected_nodes. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
The o2hb debugfs file, elapsed_time_in_ms, should return values only after the timer is armed atleast once. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
o2net messages needed a facelift. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>
Currently if the heartbeat device is hard-ro, the o2hb thread keeps chugging along and dumping errors along the way. The user needs to manually stop the heartbeat. The patch addresses this shortcoming by adding a limit to the number of times the hb thread will iterate in an unsteady state. If the hb thread does not ready steady state in that many interation, the start is aborted. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

If o2hb finds unexpected values in the heartbeat slot, it prints a message "ERROR: Device "dm-6": another node is heartbeating in our slot!" This message could be misleading. This patch adds two more messages to help users better diagnose the problem.

We have seen isolated cases (very few, I might add) of o2hb not detecting all live nodes on startup. One plausible reasoning for it is that other node had a hb io delay at the same time. The live threshold set at 2 (as low as it can be) could be increased to ameliorate the situation. But increasing the threshold directly affects mount time. Currently it takes around 5 secs to mount a volume in o2cb cluster with local heartbeat. Increasing the threshold will make mounts even slower. As the issue itself is rare, we have left things as they are for the local heartbeat mode. However we can improve the situation for global heartbeat mode as in that mode, we start the heartbeat much before the mount. This patch doubles the live threshold for the start of the first region in global heartbeat mode. Addresses internal Oracle bug#10635585.
