Clean up the various different email addresses of mine listed in the code to a single current and valid address. As Dave says his network merges for 2.6.28 are now done this seems a good point to send them in where they won't risk disrupting real changes.

2008-10-13ide: Implement disk shock protection support (v4)Elias Oltmanns1-0/+13
On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). Port resets are deferred whenever a device on that port is in the parked state. v3: Elias Oltmanns <eo@nebensachen.de> wrote: [...] > >> 1.

Additionally, we should plug the queue when enqueueing the unpark request because there is no guarantee that the park timeout has not expired by then. Even though the chance for that to happen is very slim, the request might end up hanging in the queue until the next I/O operation is queued up. While at it, clean up the code a little: - make issue_park_cmd() a function of type void since nobody cares for the return value anyway; - use blk_start_queueing() instead of __blk_run_queue() since we don't have to worry about recursion; - remove a superfluous pointer deference in task_no_data_intr().

Follow-up to commit 5c05ff68b9a9b40a9be949497e0aa980185565cf ("ide: switch to DMA-mapping API"): * pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent() in ide_{allocate,release}_dma_engine(). * Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t (+ set default values in ide_allocate_dma_engine()). * Make ide_{allocate,release}_dma_engine() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n. Then convert au1xxx-ide.c, scc_pata.c and sgiioc4.c to use them. * Add missing ->init_dma method to scc_pata. This patch also fixes: - ->dmatable_cpu leak for au1xxx-ide - too early realease of ->dmatable_cpu for scc_pata - wrong amount of ->dmatable_cpu memory being freed for sgiioc4 While at it: - remove superfluous ->dma_base check from ide_unregister() - return -ENOMEM on error in ide_release_dma_engine() - beautify error message in ide_release_dma_engine() Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

This is a much better version of a previous patch to make the parser tables constant.

Fix up the naming, style and extract some bits of code into the driver specific code Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-10-13tty: Remove more special casing and out of place codeAlan Cox2-1/+7
Carry on pushing code out of tty_io when it belongs to other drivers. I'm not 100% happy with some of this and it will be worth revisiting some of the exports later when the restructuring work is done.

2008-10-13tty: shutdown methodAlan Cox2-1/+8
Right now there are various drivers that try to use tty->count to know when they get the final close. Aristeau Rozanski showed while debugging the vt sysfs race that this isn't entirely safe. Instead of driver side tricks to work around this introduce a shutdown which is called when the tty is being destructed. This also means that the shutdown method is tied into the refcounting. Use this to rework the console close/sysfs logic. Remove lots of special case code from the tty core code. The pty code can now have a shutdown() method that replaces the special case hackery in the tree free up paths.

2008-10-13tty: the vhangup syscall is racyAlan Cox1-0/+1
We now have the infrastructure to sort this out but rather than teaching the syscall tty lock rules we move the hard work into a tty helper Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-10-13tty: usb-serial krefsAlan Cox1-0/+3
Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky. This also gives us a framework for general tty drivers to use tty_port objects and refcount. Contains two err->dev_err changes merged together to fix clashes in the -next tree.
