2006-12-08[PATCH] rename struct namespace to struct mnt_namespaceKirill Korotaev
Rename 'struct namespace' to 'struct mnt_namespace' to avoid confusion with other namespaces being developped for the containers : pid, uts, ipc, etc. 'namespace' variables and attributes are also renamed to 'mnt_ns' Signed-off-by: Kirill Korotaev <dev@sw.ru> Signed-off-by: Cedric Le Goater <clg@fr.ibm.com> Cc: Eric W.

2006-12-06NFS: Fix up writeback_control->nr_to_write accountingTrond Myklebust

2006-12-06NFS: Fix up the dirty page accountingTrond Myklebust
There is now no reason to account for the dirty pages in the NFS code, since the VM code will now do it for us via __set_page_dirty_nobuffers(), and set_page_writeback(). We still need to keep the accounting of stable writes, though. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2006-12-06NFS: Add nfs_set_page_dirty()Trond Myklebust
We will want to allow nfs_writepage() to distinguish between pages that have been marked as dirty by the VM, and those that have been marked as dirty by nfs_updatepage(). In the former case, the entire page will want to be written out, and so any requests that were pending need to be flushed out first. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-12-06NFS: Remove nfs_writepage_sync()Trond Myklebust

Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-12-06NFS: Fix asynchronous read error handlingTrond Myklebust
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.

2006-12-06NFS Exclusive open not supported bugAndy Ryan
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.

2006-11-22WorkStruct: Pass the work_struct pointer instead of context dataDavid Howells
Pass the work_struct pointer to the work function rather than context data. The work function can use container_of() to work out the data. For the cases where the container of the work_struct may go away the moment the pending bit is cleared, it is made possible to defer the release of the structure by deferring the clearing of the pending bit. To make this work, an extra flag is introduced into the management side of the work_struct. This governs auto-release of the structure upon execution. Ordinarily, the work queue executor would release the work_struct for further scheduling or deallocation by clearing the pending bit prior to jumping to the work function. This means that, unless the driver makes some guarantee itself that the work_struct won't go away, the work function may not access anything else in the work_struct or its container lest they be deallocated.. This is a problem if the auxiliary data is taken away (as done by the last patch). However, if the pending bit is *not* cleared before jumping to the work function, then the work function *may* access the work_struct and its container with no problems. But then the work function must itself release the work_struct by calling work_release(). In most cases, automatic release is fine, so this is the default. Special initiators exist for the non-auto-release case (ending in _NAR). Signed-Off-By: David Howells <dhowells@redhat.com>
2006-11-22WorkStruct: Separate delayable and non-delayable events.David Howells
Separate delayable work items from non-delayable work items be splitting them into a separate structure (delayed_work), which incorporates a work_struct and the timer_list removed from work_struct. The work_struct struct is huge, and this limits it's usefulness. On a 64-bit architecture it's nearly 100 bytes in size. This reduces that by half for the non-delayable type of event.
