2012-06-03dm thin: provide userspace access to pool metadataJoe Thornber
This patch implements two new messages that can be sent to the thin pool target allowing it to take a snapshot of the _metadata_. This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.

2012-06-03dm thin: use slab mempoolsMike Snitzer

2012-06-03dm mpath: allow ioctls to trigger pg initMikulas Patocka
After the failure of a group of paths, any alternative paths that need initialising do not become available until further I/O is sent to the device. Until this has happened, ioctls return -EAGAIN. With this patch, new paths are made available in response to an ioctl too. The processing of the ioctl gets delayed until this has happened. Instead of returning an error, we submit a work item to kmultipathd (that will potentially activate the new path) and retry in ten milliseconds. Note that the patch doesn't retry an ioctl if the ioctl itself fails due to a path failure. Such retries should be handled intelligently by the code that generated the ioctl in the first place, noting that some SCSI commands should not be retried because they are not idempotent (XOR write commands). For commands that could be retried, there is a danger that if the device rejected the SCSI command, the path could be errorneously marked as failed, and the request would be retried on another path which might fail too. It can be determined if the failure happens on the device or on the SCSI controller, but there is no guarantee that all SCSI drivers set these flags correctly.

2012-06-03dm mpath: delay retry of bypassed pgMike Christie
If I/O needs retrying and only bypassed priority groups are available, set the pg_init_delay_retry flag to wait before retrying. If, for example, the reason for the bypass is that the controller is getting reset or there is a firmware upgrade happening, retrying right away would cause a flood of log messages and retries for what could be a few seconds or even several minutes.

Pull networking updates from David Miller: 1) Make syn floods consume significantly less resources by a) Not pre-COW'ing routing metrics for SYN/ACKs b) Mirroring the device queue mapping of the SYN for the SYN/ACK reply. Both from Eric Dumazet. 2) Fix calculation errors in Byte Queue Limiting, from Hiroaki SHIMODA. 3) Validate the length requested when building a paged SKB for a socket, so we don't overrun the page vector accidently. From Jason Wang. 4) When netlabel is disabled, we abort all IP option processing when we see a CIPSO option. This isn't the right thing to do, we should simply skip over it and continue processing the remaining options (if any). Fix from Paul Moore. 5) SRIOV fixes for the mellanox driver from Jack orgenstein and Marcel Apfelbaum. 6) 8139cp enables the receiver before the ring address is properly programmed, which potentially lets the device crap over random memory.

2012-06-02tty: Revert the tty locking series, it needs more workLinus Torvalds
This reverts the tty layer change to use per-tty locking, because it's not correct yet, and fixing it will require some more deep surgery. The main revert is d29f3ef39be4 ("tty_lock: Localise the lock"), but there are several smaller commits that built upon it, they also get reverted here. The list of reverted commits is: fde86d310886 - tty: add lockdep annotations 8f6576ad476b - tty: fix ldisc lock inversion trace d3ca8b64b97e - pty: Fix lock inversion b1d679afd766 - tty: drop the pty lock during hangup abcefe5fc357 - tty/amiserial: Add missing argument for tty_unlock() fd11b42e3598 - cris: fix missing tty arg in wait_event_interruptible_tty call d29f3ef39be4 - tty_lock: Localise the lock The revert had a trivial conflict in the 68360serial.c staging driver that got removed in the meantime.

While we originally to get a much larger set of ux500 device tree enablement patches merged, this did not happen in time. After some discussion at Linaro Connect conference this week, Lee has been able to do damage control and provide a series to put the broken platform back into usable shape for both DT and non-DT based booting. This series has not been part of linux-next and is based on top of the current state of the upstream kernel rather than an -rc, but this is the best we could manage given the earlier breakage." * 'ux500/hickup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: ux500: Enable probing of pinctrl through Device Tree ARM: ux500: Add support for ab8500 regulators into the Device Tree ARM: ux500: Provide regulator support for SMSC911x via Device Tree ARM: ux500: Allow PRCMU regulator to be probed during a DT enabled boot ARM: ux500: Apply db8500-prcmu regulator information to db8500 Device Tree ARM: ux500: Only initialise STE's UIBs on boards which support them ARM: ux500: Disable platform setup of the ab8500 when DT is enabled ARM: ux500: Use correct format for dynamic IRQ assignment ARM: ux500: Re-enable SMSC911x platform code registration during non-DT boots ARM: ux500: PRCMU related configuration and layout corrections for Device Tree ARM: ux500: Remove DB8500 PRCMU platform registration when DT is enabled ARM: ux500: Disable SMSC911x platform code registration when DT is enabled ARM: ux500: New DT:ed u8500_init_devices for one-by-one device enablement ARM: ux500: New DT:ed snowball_platform_devs for one-by-one device enablement pinctrl-nomadik: Allow Device Tree driver probing

2012-06-01mtd: block2mtd: fix recursive call of mtd_writevGabor Juhos
The 'mtd_writev' interface calls the function assigned to the '_write' field of a given mtd device if that is not NULL. The block2mtd driver sets the '_writev' field to the 'mtd_writev' function itself and thus causes a endless loop. This is caused by 1dbebd32562b3c2caeca35960e5cb00bfcc12900 (mtd: harmonize mtd_writev usage). Remove the assignment from the block2mtd driver to fix the issue.
