2011-03-08nilfs2: record used amount of each checkpoint in checkpoint listRyusuke Konishi1-2/+4
This records the number of used blocks per checkpoint in each checkpoint entry of cpfile. Even though userland tools can get the block count via nilfs_get_cpinfo ioctl, it was not updated by the nilfs2 kernel code. This fixes the issue and makes it available for userland tools to calculate used amount per checkpoint. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: Jiro SEKIBA <jir@unicus.jp>
2011-03-08nilfs2: optimize rec_len functionsRyusuke Konishi1-0/+4
This is a similar change to those in ext2/ext3 codebase (commit 40a063f6691ce937 and a4ae3094869f18e2, respectively). The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks. This will cut the corner. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

2011-03-08ipv4: Cache source address in nexthop entries.David S. Miller1-2/+5
When doing output route lookups, we have to select the source address if the user has not specified an explicit one. First, if the route has an explicit preferred source address specified, then we use that. Otherwise we search the route's outgoing interface for a suitable address. This search can be precomputed and cached at route insertion time. The only missing part is that we have to refresh this precomputed value any time addresses are added or removed from the interface, and this is accomplished by fib_update_nh_saddrs().

2011-03-08net: add ndo_fcoe_ddp_target() to support FCoE DDP in target modeYi Zou1-0/+4
The Fiber Channel over Ethernet (FCoE) Direct Data Placement (DDP) can also be used for FCoE target, where the DDP used for read I/O on an initiator can be used on an FCoE target to speed up the write I/O to the target from the initiator. The added ndo_fcoe_ddp_target() works in the similar way as the existing ndo_fcoe_ddp_setup() to allow the underlying hardware set up the DDP context accordingly when it gets called from the FCoE target implementation on top the existing Open-FCoE fcoe/libfc protocol stack so without losing the ability to provide DDP for read I/O as an initiator, it can also provide DDP offload to the write I/O coming from the initiator as a target.

Add a new keyctl op to reject a key with a specified error code. This works much the same as negating a key, and so keyctl_negate_key() is made a special case of keyctl_reject_key(). The difference is that keyctl_negate_key() selects ENOKEY as the error to be reported. Typically the key would be rejected with EKEYEXPIRED, EKEYREVOKED or EKEYREJECTED, but this is not mandatory.

2011-03-08UIO: add PRUSS UIO driver supportPratheesh Gangadhar1-0/+25
This patch implements PRUSS (Programmable Real-time Unit Sub System) UIO driver which exports SOC resources associated with PRUSS like I/O, memories and IRQs to user space. PRUSS is dual 32-bit RISC processors which is efficient in performing embedded tasks that require manipulation of packed memory mapped data structures and handling system events that have tight real time constraints. This driver is currently supported on Texas Instruments DA850, AM18xx and OMAP-L138 devices. For example, PRUSS runs firmware for real-time critical industrial communication data link layer and communicates with application stack running in user space via shared memory and IRQs.

2011-03-07USB: move usbcore away from hcd->stateAlan Stern1-0/+4
The hcd->state variable is a disaster. It's not clearly owned by either usbcore or the host controller drivers, and they both change it from time to time, potentially stepping on each other's toes. It's not protected by any locks. And there's no mechanism to prevent it from going through an invalid transition. This patch (as1451) takes a first step toward fixing these problems. As it turns out, usbcore uses hcd->state for essentially only two things: checking whether the controller's root hub is running and checking whether the controller has died. Therefore the patch adds two new atomic bitflags to the hcd structure, to store these pieces of information. The new flags are used only by usbcore, and a private spinlock prevents invalid combinations (a dead controller's root hub cannot be running). The patch does not change the places where usbcore sets hcd->state, since HCDs may depend on them. Furthermore, there is one place in usb_hcd_irq() where usbcore still must use hcd->state: An HCD's interrupt handler can implicitly indicate that the controller died by setting hcd->state to HC_STATE_HALT. Nevertheless, the new code is a big improvement over the current code. The patch makes one other change. The hcd_bus_suspend() and hcd_bus_resume() routines now check first whether the host controller has died; if it has then they return immediately without calling the HCD's bus_suspend or bus_resume methods. This fixes the major problem reported in Bugzilla #29902: The system fails to suspend after a host controller dies during system resume.

With commit f363e45f we replaced a bunch of hacky workqueue mutual exclusion logic with the WQ_NON_REENTRANT flag.

In this case, we add a BACKOFF bit to make con_work reschedule delayed work next time it runs (which should be immediately). Signed-off-by: Sage Weil <sage@newdream.net>

2011-03-04perf: Add support for supplementary event registersAndi Kleen1-2/+11
Change logs against Andi's original version: - Extends perf_event_attr:config to config{,1,2} (Peter Zijlstra) - Fixed a major event scheduling issue. There cannot be a ref++ on an event that has already done ref++ once and without calling put_constraint() in between. (Stephane Eranian) - Use thread_cpumask for percore allocation. (Lin Ming) - Use MSR names in the extra reg lists. (Lin Ming) - Remove redundant "c = NULL" in intel_percore_constraints - Fix comment of perf_event_attr::config1 Intel Nehalem/Westmere have a special OFFCORE_RESPONSE event that can be used to monitor any offcore accesses from a core. This is a very useful event for various tunings, and it's also needed to implement the generic LLC-* events correctly. Unfortunately this event requires programming a mask in a separate register. And worse this separate register is per core, not per CPU thread. This patch: - Teaches perf_events that OFFCORE_RESPONSE needs extra parameters. The extra parameters are passed by user space in the perf_event_attr::config1 field. - Adds support to the Intel perf_event core to schedule per core resources. This adds fairly generic infrastructure that can be also used for other per core resources. The basic code has is patterned after the similar AMD northbridge constraints code.

2011-03-04LSM: Pass -o remount options to the LSMEric Paris1-0/+13
The VFS mount code passes the mount options to the LSM. The LSM will remove options it understands from the data and the VFS will then pass the remaining options onto the underlying filesystem. This is how options like the SELinux context= work. The problem comes in that -o remount never calls into LSM code. So if you include an LSM specific option it will get passed to the filesystem and will cause the remount to fail. An example of where this is a problem is the 'seclabel' option. The SELinux LSM hook will print this word in /proc/mounts if the filesystem is being labeled using xattrs. If you pass this word on mount it will be silently stripped and ignored. But if you pass this word on remount the LSM never gets called and it will be passed to the FS. The FS doesn't know what seclabel means and thus should fail the mount. For example an ext3 fs mounted over loop # mount -o loop /tmp/fs /mnt/tmp # cat /proc/mounts | grep /mnt/tmp /dev/loop0 /mnt/tmp ext3 rw,seclabel,relatime,errors=continue,barrier=0,data=ordered 0 0 # mount -o remount /mnt/tmp mount: /mnt/tmp not mounted already, or bad option # dmesg EXT3-fs (loop0): error: unrecognized mount option "seclabel" or missing value This patch passes the remount mount options to an new LSM hook.

2011-03-03ASoC: Add a late_probe() callback to cardsMark Brown1-0/+1
This is run after the DAPM widgets and routes are added, allowing setup of things like jacks using the routes. The main card probe() is run before anything else so can't be used for this purpose.

2011-03-03ASoC: Allow card DAPM widgets and routes to be set up at registrationMark Brown1-0/+8
These will be added after all devices are registered and allow most DAI init functions in machine drivers to be replaced by simple data. Regular controls are not supported as the registration function still works in terms of CODECs.

2011-03-03ASoC: Add a per-card DAPM contextMark Brown1-0/+3
This means that rather than adding the board specific DAPM widgets to a random CODEC DAPM context they can be added to the card itself which is a bit cleaner. Previously there only was one DAPM context and it was tied to the single supported CODEC. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
