2011-11-22freezer: unexport refrigerator() and update try_to_freeze() slightlyTejun Heo1-6/+6
There is no reason to export two functions for entering the refrigerator. Calling refrigerator() instead of try_to_freeze() doesn't save anything noticeable or removes any race condition. * Rename refrigerator() to __refrigerator() and make it return bool indicating whether it scheduled out for freezing. * Update try_to_freeze() to return bool and relay the return value of __refrigerator() if freezing(). * Convert all refrigerator() users to try_to_freeze(). * Update documentation accordingly. * While at it, add might_sleep() to try_to_freeze().

2011-11-22freezer: don't unnecessarily set PF_NOFREEZE explicitlyTejun Heo1-1/+1
Some drivers set PF_NOFREEZE in their kthread functions which is completely unnecessary and racy - some part of freezer code doesn't consider cases where PF_NOFREEZE is set asynchronous to freezer operations. In general, there's no reason to allow setting PF_NOFREEZE explicitly. Remove them and change the documentation to note that setting PF_NOFREEZE directly isn't allowed. -v2: Dropped change to twl4030-irq.c as it no longer uses PF_NOFREEZE.

2011-11-16cciss: auto engage SCSI mid layer at driver load timeStephen M. Cameron1-8/+6
A long time ago, probably in 2002, one of the distros, or maybe more than one, loaded block drivers prior to loading the SCSI mid layer. This meant that the cciss driver, being a block driver, could not engage the SCSI mid layer at init time without panicking, and relied on being poked by a userland program after the system was up (and the SCSI mid layer was therefore present) to engage the SCSI mid layer. This is no longer the case, and cciss can safely rely on the SCSI mid layer being present at init time and engage the SCSI mid layer straight away. This means that users will see their tape drives and medium changers at driver load time without need for a script in /etc/rc.d that does this: for x in /proc/driver/cciss/cciss* do echo "engage scsi" > $x done However, if no tape drives or medium changers are detected, the SCSI mid layer will not be engaged. If a tape drive or medium change is later hot-added to the system it will then be necessary to use the above script or similar for the device(s) to be acceesible. Signed-off-by: Stephen M.

2011-11-10block: Revert "[SCSI] genhd: add a new attribute "alias" in gendisk"Tejun Heo1-13/+0
This reverts commit a72c5e5eb738033938ab30d6a634b74d1d060f10. The commit introduced alias for block devices which is intended to be used during logging although actual usage hasn't been committed yet. This approach adds very limited benefit (raw log might be easier to follow) which can be trivially implemented in userland but has a lot of problems. It is much worse than netif renames because it doesn't rename the actual device but just adds conveninence name which isn't used universally or enforced. Everything internal including device lookup and sysfs still uses the internal name and nothing prevents two devices from using conflicting alias - ie. sda can have sdb as its alias. This has been nacked by people working on device driver core, block layer and kernel-userland interface and shouldn't have been upstreamed. Revert it. http://thread.gmane.org/gmane.linux.kernel/1155104 http://thread.gmane.org/gmane.linux.scsi/68632 http://thread.gmane.org/gmane.linux.scsi/69776 Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Acked-by: Kay Sievers <kay.sievers@vrfy.org> Cc: "James E.J.

2011-11-07ACPI: Export FADT pm_profile integer value to userspaceThomas Renninger1-0/+22
There are a lot userspace approaches to detect the usage of the platform (laptop, workstation, server, ...) and adjust kernel tunables accordingly (io/process scheduler, power management, ...). These approaches need constant maintaining and are ugly to implement (detect PCMCIA controller -> laptop, does not work on recent systems anymore, ...) On ACPI systems there is an easy and reliable way (if implemented in BIOS and most recent platforms have this value set). -> export it to userspace.

2011-11-05PM / Runtime: Automatically retry failed autosuspendsAlan Stern1-0/+10
Originally, the runtime PM core would send an idle notification whenever a suspend attempt failed. The idle callback routine could then schedule a delayed suspend for some time later. However this behavior was changed by commit f71648d73c1650b8b4aceb3856bebbde6daa3b86 (PM / Runtime: Remove idle notification after failing suspend). No notifications were sent, and there was no clear mechanism to retry failed suspends. This caused problems for the usbhid driver, because it fails autosuspend attempts as long as a key is being held down. Therefore this patch (as1492) adds a mechanism for retrying failed autosuspends. If the callback routine updates the last_busy field so that the next autosuspend expiration time is in the future, the autosuspend will automatically be rescheduled.

2011-11-04hwmon: (w83627ehf) Add support for the W83627UHGJean Delvare1-13/+15
This is essentially a stripped down version of the W83627DHG. Noticeable difference is that it is still powered with +5V, as older models, even though the ADC resolution is 8 mV as newer models have. Thanks to Ulf Bruman (Saab Group) for doing all the testing. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>

2011-11-04[media] v4l: Add AUTO option for the V4L2_CID_POWER_LINE_FREQUENCY controlSylwester Nawrocki1-2/+3
V4L2_CID_POWER_LINE_FREQUENCY control allows applications to instruct a driver what is the power line frequency so an appropriate filter can be used by the device to cancel flicker by compensating the light intensity ripple. Currently in the menu we have entries for 50 Hz and 60 Hz and for entirely disabling the anti-flicker filter. However some devices are capable of automatically detecting the frequency, so add V4L2_CID_POWER_LINE_FREQUENCY_AUTO entry for them.

2011-11-03memcg: skip scanning active lists based on individual sizeJohannes Weiner1-1/+0
Reclaim decides to skip scanning an active list when the corresponding inactive list is above a certain size in comparison to leave the assumed working set alone while there are still enough reclaim candidates around. The memcg implementation of comparing those lists instead reports whether the whole memcg is low on the requested type of inactive pages, considering all nodes and zones. This can lead to an oversized active list not being scanned because of the state of the other lists in the memcg, as well as an active list being scanned while its corresponding inactive list has enough pages. Not only is this wrong, it's also a scalability hazard, because the global memory state over all nodes and zones has to be gathered for each memcg and zone scanned. Make these calculations purely based on the size of the two LRU lists that are actually affected by the outcome of the decision.
