This fixes sparse warnings such as: .../o2iblnd.c:424:1: warning: symbol 'kiblnd_get_peer_info' was not declared. Should it be static? This reduces the code size by 400 bytes. The body of "the_o2iblnd" was moved at the end of the file, to avoid having to declare some static prototypes. Signed-off-by: -

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:

Currently the socklnd driver doesn't support CPT affinity for its peers. Binding peers to a specific CPT and memory allocated to the NUMA node belonging to the CPT should give a performance boost. 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:

In lnet_ptl_match_delay() we check msg->msg_rx_delayed to see whether the message has been added to the delay queue. But this check is done after lnet_ptl_unlock() and lnet_res_unlock(), and the message can be processed and freed before the check. Replace the check with checking rc against LNET_MATCHMD_NONE, which is how the callers of lnet_ptl_match_delay() know whether the message was added to the delay queue. To make this work we reset rc in the loop when there was no match and the message hasn't been delayed. In addition reorganize the code and add comments to clarify the logic. In lnet_ptl_match_md() a similar msg->msg_rx_delayed is replaced for the same reason. Signed-off-by:

Since the # of hops is not a mandatory parameter the LU-6060 patch will cause problems to already existing systems since it changes the behavior by which a route is determined down. To fix this case the # of hops now defaults to LNET_UNDEFINED_HOPS if no hop count is specified. LNET_UNDEFINED_HOPS is defined to ((__u32)-1). When it's printed as %d, it displays as -1. __u32 is used through out the call stack for hop count to explicitly define the size of the hop count and to avoid any sizing issues when passing data to and from the kernel. To keep existing behavior both lnet_compare_routes() and LNetDist() will treat undefined hop count as hop count 1. When executing the logic in lnet_parse_rc_info() there is no longer an assumption that the default hop count is 1. If the hop count is 1 then it must've been explicitly set by the user.

When lnet_parse_put calls lnet_ptl_match_md, this function can attach current message on the delayed list if there is no match. It means this message can be taken over and freed by another thread who is posting new MD, then it is not safe for caller of lnet_parse_put to check this message again. This patch fixes this issue by adding a local variable "ready_delay" to store corresponding status of lnet_msg, so lnet doesn't need to check the message again if lnet_ptl_match_md returned MATCH_NONE for it.
