| * | | | | mmc: add DMA support to tmio_mmc driver, when used on SuperHGuennadi Liakhovetski2010-05-223-30/+348
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SDHI controllers on SuperH, served by the tmio_mmc driver, can use slave DMA for data transfer. This patch adds support for the dmaengine API to the tmio_mmc driver.

Add the missing parts. This is actually an optimization, by using __set_page_dirty_nobuffers. The default, in case of NULL, would be __set_page_dirty_buffers which has these extar if(s). .releasepage && .invalidatepage should both not be called because page_private() is NULL in exofs. Put a WARN_ON if they are called, to indicate the Kernel has changed in this regard, if when it does. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

NetworkManager thinks everything is ok, but it can't connect to the AP to get an IP address after the resume. In fact, it even breaks resume for non-ath9k chipsets: reverting it also fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes says: "Indeed, this patch needs to be reverted.

If we remove the last cap, and there are no cap migrations in progress, then there is little hope of us flushing out that data to the mds (without heroic efforts to reconnect and flush). So, to avoid leaving inodes pinned (due to dirty state) and crashing after umount, throw out dirty caps state and unpin the inodes. Print a warning to the console so we know something was lost. NOTE: Although we drop wrbuffer refs, we don't actually mark pages clean; maybe a truncate should be queued? Signed-off-by: Sage Weil <sage@newdream.net>

Change client to attempt an immediate reconnect if our session is closed. Note that currently the MDS doesn't support this, and our attempt will fail. We'll get a session CLOSE, our caps and dirty cap state will be dropped, and the client will be free to attempt to reconnect. That's clearly not as nice as a successful reconnect, but it at least allows us to try to carry on, and in the future the MDS will support a reconnect and we will fare better.

Remove the dead code for sending empty reconnects. It used to be used when the MDS contacted _us_ to solicit a reconnect, and we could reply saying "go away, I have no session." Now we only send reconnects based on the mds map, and only when we do in fact have an open session. Signed-off-by: Sage Weil <sage@newdream.net>

That wasn't particularly reliable. Instead, the MDS replies with an explicit OPEN message to indicate success. Strictly speaking, this is a protocol change, but it is a backwards compatible one that does not break new clients + old servers or old clients + new servers. At least not yet. Drop unused @all argument from kick_requests while we're at it. Signed-off-by: Sage Weil <sage@newdream.net>

This patch switches the client to the new scheme, and _requires_ this feature on the server. The server will support both the old and new schemes. That means an old client will work with a new server, but a new client will not work with an old server. Signed-off-by: Sage Weil <sage@newdream.net>
