2008-10-10[S390] xpram: per device block request queues.Martin Schwidefsky
The xpram driver uses a single block device queue for all of its devices so far. With recent kernels removing xpram module fails to clean up all sysfs files. The next time the xpram module is loaded you'll get warnings: WARNING: at fs/sysfs/dir.c:463 sysfs_add_one+0x5e/0x64() sysfs: duplicate filename '35:0' can not be created Modules linked in: xpram(+) [last unloaded: xpram] Followed by the usual WARN_ON output, followed by an error message from kobject_add_internal, followed by a badness in genhd. Allocating a block queue per device fixes this. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2008-10-10[S390] cio: Correct use of ! and &Julia Lawall
In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. In particular, the result of !scsw_stctl(&request->irb.scsw) & SCSW_STCTL_STATUS_PEND is always just !scsw_stctl(&request->irb.scsw). The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E; constant C; @@ ( !E & !C | - !E & C + !(E & C) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2008-10-10[S390] qdio: speed up multicast traffic on full HiperSocket queueUrsula Braun
If an asynchronous HiperSockets queue runs full, no further packet can be sent. In this case the next initiative to give transmitted skbs back to the stack is triggered only by a 10-seconds qdio timer. This timer has been introduced for low multicast traffic scenarios to guarantee freeing of skbs in a limited amount of time. For high HiperSocket multicast traffic scenarios progress checking on the outbound queue should be enforced by tasklet rescheduling.

2008-10-10PnP: move pnpacpi/pnpbios_init to after PCI initLinus Torvalds
We already did that a long time ago for pnp_system_init, but pnpacpi_init and pnpbios_init remained as subsys_initcalls, and get linked into the kernel before the arch-specific routines that finalize the PCI resources (pci_subsys_init). This means that the PnP routines would either register their resources before the PCI layer could, or would be unable to check whether a PCI resource had already been registered. Both are problematic. I wanted to do this before 2.6.27, but every time we change something like this, something breaks. That said, _every_ single time we trust some firmware (like PnP tables) more than we trust the hardware itself (like PCI probing), the problems have been worse.

2008-10-10dm crypt: avoid unnecessary wait when splitting bioMilan Broz
Don't wait between submitting crypt requests for a bio unless we are short of memory. There are two situations when we must split an encrypted bio: 1) there are no free pages; 2) the new bio would violate underlying device restrictions (e.g. max hw segments). In case (2) we do not need to wait. Add output variable to crypt_alloc_buffer() to distinguish between these cases.

2008-10-10dm raid1: kcopyd should stop on error if errors handledJonathan Brassow
dm-raid1 is setting the 'DM_KCOPYD_IGNORE_ERROR' flag unconditionally when assigning kcopyd work. kcopyd is responsible for copying an assigned section of disk to one or more other disks. The 'DM_KCOPYD_IGNORE_ERROR' flag affects kcopyd in the following way: When not set: kcopyd will immediately stop the copy operation when an error is encountered. When set: kcopyd will try to proceed regardless of errors and try to continue copying any remaining amount. Since dm-raid1 tracks regions of the address space that are (or are not) in sync and it now has the ability to handle these errors, we can safely enable this optimization. This optimization is conditional on whether mirror error handling has been enabled. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

This patch allows path errors from the multipath ctr function to propagate up to userspace as errno values from the ioctl() call. This is in response to https://www.redhat.com/archives/dm-devel/2008-May/msg00000.html and https://bugzilla.redhat.com/show_bug.cgi?id=444421 The patch only lets through the errors that it needs to in order to get the path errors from parse_path().

2008-10-09RDMA/nes: Fix slab corruptionChien Tung
Referencing cm_node after it is freed via rem_ref_cm_node() causes a slab corruption. There is no need to set cm_node->cm_id to NULL in mini_cm_close(). Signed-off-by: Chien Tung <ctung@neteffect.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-10-09hwmon: (abituguru3) Enable DMI probing feature on Abit AT8 32XAlistair John Strachan
Enable driver checking of the DMI product name (when enabled) on an Abit AT8 32X, instead of falling back to a manual probe. This eliminates false negatives and eventually will help avoid unnecessary bus probes on unsupported mainboards.

2008-10-09hwmon: (abituguru3) Enable reading from AUX3 fan on Abit AT8 32XAlistair John Strachan
The table for the Abit AT8 32X was incorrectly missing an entry for the sixth ("AUX3") fan. Add this entry, exporting the fan reading to userspace. Closes lm-sensors.org ticket #2339.

2008-10-09hwmon: (it87) Prevent power-off on Shuttle SN68PTJean Delvare
On the Shuttle SN68PT, FAN_CTL2 is apparently not connected to a fan, but to something else. One user has reported instant system power-off when changing the PWM2 duty cycle, so we disable it. I use the board name string as the trigger in case the same board is ever used in other systems. This closes lm-sensors ticket #2349: pwmconfig causes a hard poweroff http://www.lm-sensors.org/ticket/2349 Signed-off-by: Jean Delvare <khali@linux-fr.org>

Creates a name file in the sysfs directory, that is needed for the libsensors library to work. Also rename fan1_pwm to pwm1 and scale its value as needed.

2008-10-09block: mark bio_split_pool staticDenis ChengRq
Since all bio_split calls refer the same single bio_split_pool, the bio_split function can use bio_split_pool directly instead of the mempool_t parameter; then the mempool_t parameter can be removed from bio_split param list, and bio_split_pool is only referred in fs/bio.c file, can be marked static.

2008-10-09gdrom: change to use __blk_end_request()Kiyoshi Ueda
This patch converts gdrom to use __blk_end_request() directly so that end_{queued|dequeued}_request() can be removed. gd.transfer is '1' in error cases and '0' in non-error cases, so gdrom hasn't been propagating any error code to the block layer. We can just convert error cases to '-EIO'.
