2010-03-05dquot: cleanup dquot transfer routineChristoph Hellwig
Get rid of the transfer dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_transfer helper to __dquot_transfer and vfs_dq_transfer to dquot_transfer to have a consistent namespace, and make the new dquot_transfer return a normal negative errno value which all callers expect.

2010-03-01sata_via: Delay on vt6420 when starting ATAPI DMA writeBart Hartgers
When writing a disc on certain lite-on dvd-writers (also rebadged as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends up in the datastream and on the disc, causing silent corruption. Delaying between sending the CDB and starting DMA seems to prevent this. I do not know if there are burners that do not suffer from this, but the patch should be safe for those as well. There are many reports of this issue, but AFAICT no solution was found before.

Before only the timings for master were set. Datasheet can be found here: ftp://ftp.vtbridge.org/Docs/Storage/DS_VT6421A_100_CCPL.PDF Surprisingly, a slave drive works without this patch. According to the datasheet, the controller by default derives the DMA mode from the Set Features command issued to a drive. Not sure about the PIO timings, though. The real problem is that the timings for the master effectively are the ones tuned for the slave. If these support different UDMA-settings, there is trouble, especially when the slave supports a higher UDMA than the master. Anyhow, using the same mechanism for both master and slave seems like a good idea.

2010-03-01libata: implement spurious irq handling for SFF and apply it to piixTejun Heo
Traditional IDE interface sucks in that it doesn't have a reliable IRQ pending bit, so if the controller raises IRQ while the driver is expecting it not to, the IRQ won't be cleared and eventually the IRQ line will be killed by interrupt subsystem. Some controllers have non-standard mechanism to indicate IRQ pending so that this condition can be detected and worked around. This patch adds an optional operation ->sff_irq_check() which will be called for each port from the ata_sff_interrupt() if an unexpected interrupt is received. If the operation returns %true, ->sff_check_status() and ->sff_irq_clear() will be cleared for the port. Note that this doesn't mark the interrupt as handled so it won't prevent IRQ subsystem from killing the IRQ if this mechanism fails to clear the spurious IRQ. This patch also implements ->sff_irq_check() for ata_piix. Note that this adds slight overhead to shared IRQ operation as IRQs which are destined for other controllers will trigger extra register accesses to check whether IDE interrupt is pending but this solves rare screaming IRQ cases and for some curious reason also helps weird BIOS related glitch on Samsung n130 as reported in bko#14314. http://bugzilla.kernel.org/show_bug.cgi?id=14314 * piix_base_ops dropped as suggested by Sergei. * Spurious IRQ detection doesn't kick in anymore if polling qc is in progress. This provides less protection but some controllers have possible data corruption issues if the wrong register is accessed while a command is in progress.
