Use of init_rcu_head() and destroy_rcu_head() from modules results in the following build-time error with CONFIG_DEBUG_OBJECTS_RCU_HEAD=y: ERROR: "init_rcu_head" [drivers/scsi/scsi_mod.ko] undefined! ERROR: "destroy_rcu_head" [drivers/scsi/scsi_mod.ko] undefined! This commit therefore adds EXPORT_SYMBOL_GPL() for each to allow them to be used by GPL-licensed kernel modules. Reported-by:

We are testing if there is a match with the ses device in a loop by calling ses_match_to_enclosure(), which will issue scsi receive diagnostics commands to the ses device for every device on the same host. On one of our boxes with 840 disks, it takes a long time to load the driver: [root@g1b-oss06 ~]# time modprobe ses real 40m48.247s user 0m0.001s sys 0m0.196s With the patch: [root@g1b-oss06 ~]# time modprobe ses real 0m17.915s user 0m0.008s sys 0m0.053s Note that we still need to refresh page 10 when we see a new disk to create the link.

The logic for sg_seg_cnt is a bit convoluted. This patch tries to clean up a couple of areas, especially around the +2 and +1 logic. This patch: - Cleans up the lpfc_sg_seg_cnt attribute to specify a real minimum rather than making the minimum be whatever the default is. - Removes the hardcoding of +2 (for the number of elements we use in a sgl for cmd iu and rsp iu) and +1 (an additional entry to compensate for nvme's reduction of io size based on a possible partial page) logic in sg list initialization. In the case where the +1 logic is referenced in host and target io checks, use the values set in the transport template as that value was properly set. There can certainly be more done in this area and it will be addressed in combined host/target driver effort. Signed-off-by:

During driver unload, the driver may crash due to NULL pointers. The NULL pointers were due to the driver not protecting itself sufficiently during some of the teardown paths. Additionally, the driver was not waiting for and cleanup up nvme io resources. As such, the driver wasn't making the callbacks to the transport, stalling the transports association teardown. This patch waits for io clean up before tearding down and adds checks for possible NULL pointers. Cc: <stable@vger.kernel.org> # 4.12+ Signed-off-by:

When the driver is unloading, the nvme transport could be in the process of submitting new requests, will send abort requests to terminate associations, or may make LS-related requests. The driver's abort and request entry points currently is ignorant of the unloading state and is starting the requests even though the infrastructure to complete them continues to teardown. Change the entry points for new requests to check whether unloading and if so, reject the requests. Abort routines check unloading, and if so, noop the request. An abort is noop'd as the teardown paths are already aborting/terminating the io outstanding at the time the teardown initiated. Signed-off-by:

The driver's interaction with the host nvme transport has been incorrect for a while. The driver did not wait for the unregister callbacks (waited only 5 jiffies). Thus the driver may remove objects that may be referenced by subsequent abort commands from the transport, and the actual unregister callback was effectively a noop. This was especially problematic if the driver was unloaded. The driver now waits for the unregister callbacks, as it should, before continuing with teardown. Signed-off-by:

During RSCN storms, the driver does not rediscover some targets. The driver marks some RSCN as to be handled after the ones it's working on. The driver missed processing some deferred RSCN. Move where the driver checks for deferred RSCNs and initiate deferred RSCN handling if the flag was set. Also revise nport state within the RSCN confirm routine. Add some state data to a possible debug print to aid future debugging. Signed-off-by:
