The SuS states that a call to write() will cause mtime to be updated on the file. In order to satisfy that requirement, we need to flush out any cached writes in nfs_getattr(). Speed things up slightly by not committing the writes. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Most NFS server implementations allow up to 64KB reads and writes on the wire. The Solaris NFS server allows up to a megabyte, for instance. Now the Linux NFS client supports transfer sizes up to 1MB, too. This will help reduce protocol and context switch overhead on read/write intensive NFS workloads, and support larger atomic read and write operations on servers that support them. Test-plan: Connectathon and iozone on mount point with wsize=rsize>32768 over TCP. Tests with NFS over UDP to verify the maximum RPC payload size cap.

Replace ad hoc write parameter sanity checking in nfs_file_direct_write() with a call to generic_write_checks(). This should make the proper checks modulo the O_LARGEFILE flag, and should catch NFSv2-specific limitations by virtue of i_sb->s_maxbytes.

In RFC3530, the RENEW operation is allowed to use either the same principal, RPC security flavour and (if RPCSEC_GSS), the same mechanism and service that was used for SETCLIENTID_CONFIRM OR Any principal, RPC security flavour and service combination that currently has an OPEN file on the server. Choose the latter since that doesn't require us to keep credentials for the same principal for the entire duration of the mount. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

When recovering from a delegation recall or a network partition, we need to replay open(O_RDWR), open(O_RDONLY) and open(O_WRONLY) separately. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

由 Trond Myklebust 提交于
A closer reading of RFC3530 reveals that OPEN_DOWNGRADE must always specify a access modes that have been the argument of a previous OPEN operation. IOW: doing OPEN(O_RDWR) and then OPEN_DOWNGRADE(O_WRONLY) is forbidden unless the user called OPEN(O_WRONLY) In order to fix that, we really need to track the three possible open states separately.

OPEN is a stateful operation, so we must ensure that it always completes. In order to allow users to interrupt the operation, we need to make the RPC call asynchronous, and then wait on completion (or cancel). Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

The NFSv4 model requires us to complete all RPC calls that might establish state on the server whether or not the user wants to interrupt it. We may also need to schedule new work (including new RPC calls) in order to cancel the new state. The asynchronous RPC model will allow us to ensure that RPC calls always complete, but in order to allow for "synchronous" RPC, we want to add the ability to wait for completion. The waits are, of course, interruptible. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Shrink the RPC task structure. Instead of storing separate pointers for task->tk_exit and task->tk_release, put them in a structure. Also pass the user data pointer as a parameter instead of passing it via task->tk_calldata. This enables us to nest callbacks. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Ensure that we always initiate flushing of data before we exit a single-page ->writepage() call. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>
-
由 Andrew Morton 提交于
NFS needs to be able to distinguish between single-page ->writepage() calls and multipage ->writepages() calls. For the single-page writepage calls NFS can kick off the I/O within the context of ->writepage(). For multipage ->writepages calls, nfs_writepage() will leave the I/O pending and nfs_writepages() will kick off the I/O when it all has been queued up within NFS.

This was harmless, but for the case of a device that had no irq pre-defined we would incorrectly suggest that "usepirqmask" might make a difference. It never would, and the message was just confusing people. Reported in the dmesg of Etienne Lorrain. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.
