rds_rdma: don't assume infiniband device is PCI

2012-05-29T21:30:07Z

RDS code assumes that the struct ib_device dma_device member, which is a pointer, points to a struct device embedded in a struct pci_dev. This is not the case for ehca, for example, which is a OF driver, and makes dma_device point to a struct device embedded in a struct platform_device. This will make the system crash when rds_rdma is loaded in a system with ehca, since it will try to access the bus member of a non-existent struct pci_dev. The only reason rds_rdma uses the struct pci_dev is to get the NUMA node the device is attached to. Using dev_to_node for that is much better, since it won't assume which bus the infiniband is attached to.

net: remove interrupt.h inclusion from netdevice.h

* remove interrupt.g inclusion from netdevice.h -- not needed * fixup fallout, add interrupt.h and hardirq.h back where needed. Signed-off-by: Alexey Dobriyan Signed-off-by: David S. Miller

rds/ib: use system_wq instead of rds_ib_fmr_wq

2011-02-01T10:42:43Z

With cmwq, there's no reason to use dedicated rds_ib_fmr_wq - it's not in the memory reclaim path and the maximum number of concurrent work items is bound by the number of devices. Drop it and use system_wq instead. This rds_ib_fmr_init/exit() noops. Both removed. Signed-off-by: Tejun Heo Cc: Andy Grover

rds: make local functions/variables static

2010-10-21T11:26:39Z

The RDS protocol has lots of functions that should be declared static. rds_message_get/add_version_extension is removed since it defined but never used. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

RDS/IB: print string constants in more places

2010-09-09T01:16:50Z

This prints the constant identifier for work completion status and rdma cm event types, like we already do for IB event types. A core string array helper is added that each string type uses. Signed-off-by: Zach Brown

RDS/IB: protect the list of IB devices

2010-09-09T01:16:44Z

The RDS IB device list wasn't protected by any locking. Traversal in both the get_mr and FMR flushing paths could race with additon and removal. List manipulation is done with RCU primatives and is protected by the write side of a rwsem. The list traversal in the get_mr fast path is protected by a rcu read critical section. The FMR list traversal is more problematic because it can block while traversing the list. We protect this with the read side of the rwsem. Signed-off-by: Zach Brown

RDS/IB: track signaled sends

2010-09-09T01:16:40Z

We're seeing bugs today where IB connection shutdown clears the send ring while the tasklet is processing completed sends. Implementation details cause this to dereference a null pointer. Shutdown needs to wait for send completion to stop before tearing down the connection. We can't simply wait for the ring to empty because it may contain unsignaled sends that will never be processed. This patch tracks the number of signaled sends that we've posted and waits for them to complete. It also makes sure that the tasklet has finished executing. Signed-off-by: Zach Brown

RDS: remove init and exit annotation

The trivial amount of memory saved isn't worth the cost of dealing with section mismatches. Signed-off-by: Zach Brown

RDS/IB: create a work queue for FMR flushing

2010-09-09T01:16:34Z

This patch moves the FMR flushing work in to its own mult-threaded work queue. This is to maintain performance in preparation for returning the main krdsd work queue back to a single threaded work queue to avoid deep-rooted concurrency bugs. This is also good because it further separates FMRs, which might be removed some day, from the rest of the code base. Signed-off-by: Zach Brown
