Add support for setting and retrieving OverSampling Rate independently for each of the temperature and pressure channels. This allows userspace to fine tune hardware sampling process according to the following tradeoffs : * the higher the OSR, the finer the resolution ; * the higher the OSR, the lower the noise ; BUT: * the higher the OSR, the larger the drift ; * the higher the OSR, the longer the response time, i.e. less samples per unit of time.

When there is a connection race between two nodes and one side of the connection is rejected by the other side. o2iblnd will reconnect immediately, this is going to generate a lot of trashes if: - race winner is slow and can't send out connecting request in short time. - remote side leaves a cmid in TIMEWAIT state, which will reject future connection requests To resolve this problem, this patch changed the reconnection behave: reconnection is submitted by connd only if a zombie connection is being destroyed and there is a pending reconnection request for the corresponding peer. Also, after a few rejections, reconnection will have a time interval between each attempt. Signed-off-by:

If ib_poll_cq returned +ve without initialising ib_wc::wr_id (bug in driver), then o2iblnd will run into unpredictable situation because ib_wc::wr_id may refer to stale tx/rx pointer in stack. It indicates bug in HCA driver if this happened, ko2iblnd should output console error then close current connection. This patch could also be helpful for LU-5271 Signed-off-by:

A race condition has been found where connd is cleaning up failed connections, the peer ref counter goes to zero, but we stil have a connecting counter > 0. One possible race is when we are retrying a connection by calling kiblnd_connect_peer() which itself fails and decrements the peer ref counter and gets swapped out before it can decrement the connecting counter. connd swaps in and cleans up the connection where it sees a peer ref counter of 1 and a connecting counter of 1. This will trigger the assert seen in LU-7210 when it decrements the peer counter. The solution: be sure to decrement the connecting counter before decrementing the peer counter in the peer connect failure path. Signed-off-by:

refcount taken by cmid is not reliable after kiblnd_connreq_done released the glock because this connection is visible to other threads, another thread can find and close this connection right after kiblnd_connreq_done released the glock, if kiblnd_cm_callback for RDMA_CM_EVENT_DISCONNECTED is called, it can release the connection refcount taken by cmid. It means the connection could be destroyed before kiblnd_connreq_done() finish operations on it. Signed-off-by:

Store map-on-demand and peertx credits in the peer, since the peer is persistent. Also made sure that when assigning the parameters received on the connection to the peer structure through create, that if another peer is added before grabbing the lock we assign these parameters to it as well.

LNet is an abstraction built on top of network APIs such as infiniband or TCP/IP layer. Since LNet is dependent on these other layers we should ensure LNet headers should always come after the infiniband header since the infiniband headers can influence the LNet header definitions. Signed-off-by:

On some customers' systems, the kernel was compiled with HZ defined to 100, instead of 1000. This improves performance for HPC applications. However, to use these systems with Lustre, customers have to re-build Lustre for the kernel because Lustre directly uses the defined constant HZ. Since kernel 2.6.21, some non-HZ dependent timing APIs become non- inline functions, which can be used in Lustre codes to replace the direct HZ access. These kernel APIs include: jiffies_to_msecs() jiffies_to_usecs() jiffies_to_timespec() msecs_to_jiffies() usecs_to_jiffies() timespec_to_jiffies() And here are some samples of the replacement: HZ -> msecs_to_jiffies(MSEC_PER_SEC) n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC) HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n) n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC n / HZ * 1000 -> jiffies_to_msecs(n) This patch replaces the direct HZ access in lnet module.

In the original code change when libcfs_sock_accept() was made into lnet_sock_accept() a call to set_current_state(TASK_INTERRUPTIBLE) got dropped which was restored. For upstream this is an optimization of calling init_waitqueue_entry() only if accept() return -EAGAIN. Also we can remove setting the task to TASK_RUNNING that is not needed. Signed-off-by:
