We always ensure that the nfs_open_context holds a reference to the dentry, so the test in nfs_writepage() for whether or not the inode is referenced is redundant. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Change the location where the rpc_xprt structure is allocated so each transport implementation can allocate a private area from the same chunk of memory. Note also that xprt->ops->destroy, rather than xprt_destroy, is now responsible for freeing rpc_xprt when the transport is destroyed. Test plan: Connectathon.

We must always call ->read_done() before we truncate the page data, or decide to flag an error. The reasons are that in NFSv2, ->read_done() is where the eof flag gets set. in NFSv3/v4 ->read_done() handles EJUKEBOX-type errors, and v4 state recovery. However, we need to mark the pages as uptodate before we deal with short read errors, since we may need to modify the nfs_read_data arguments. We therefore split the current nfs_readpage_result() into two parts: nfs_readpage_result(), which calls ->read_done() etc, and nfs_readpage_retry(), which subsequently handles short reads. Note: Removing the code that retries in case of a short read also fixes a bug in nfs_direct_read_result(), which used to return a corrupted number of bytes.

When trying to open a file with the O_EXCL flag over NFS on a server that does not support exclusive mode, the file does not open. The reason, rpc_call_sync returns a errno number, and not the nfs error number. I fixed it by changing the status check in nfs3proc.c. Either this is how it should be fixed, or rpc_call_sync should be fixed to return the NFS error.

Use RCU to ensure that we can safely call rpc_finish_wakeup after we've called __rpc_do_wake_up_task. If not, there is a theoretical race, in which the rpc_task finishes executing, and gets freed first. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

The sunrpc scheduler contains a race condition that can let an RPC task end up being neither running nor on any wait queue. The race takes place between rpc_make_runnable (called from rpc_wake_up_task) and __rpc_execute under the following condition: First __rpc_execute calls tk_action which puts the task on some wait queue. The task is dequeued by another process before __rpc_execute continues its execution. While executing rpc_make_runnable exactly after setting the task `running' bit and before clearing the `queued' bit __rpc_execute picks up execution, clears `running' and subsequently both functions fall through, both under the false assumption somebody else took the job. Swapping rpc_test_and_set_running with rpc_clear_queued in rpc_make_runnable fixes that hole. This introduces another possible race condition that can be handled by checking for `queued' after setting the `running' bit. Bug noticed on a 4-way x86_64 system under XEN with an NFSv4 server on the same physical machine, apparently one of the few ways to hit this race condition at all.

megaraid's MMIO RD*/WR* macros directly call readl() and writel() with an 'unsigned long' argument. This throws a warning, but is otherwise OK because the 'unsigned long' is really the result of ioremap(). This setup is also OK because the variable can hold an ioremap cookie /or/ a PCI I/O port (PIO). However, to fix the warning thrown when readl() and writel() are passed an unsigned long cookie, I introduce 'void __iomem *mmio_base', holding the same value as 'base'. This will silence the warnings, and also cause an oops whenever these MMIO-only functions are ever accidentally passed an I/O address.
