2010-12-17cgroup: Set CGRP_RELEASABLE when adding to a cgroupColin Cross
Changes the meaning of CGRP_RELEASABLE to be set on any cgroup that has ever had a task or cgroup in it, or had css_get called on it. The bit is set in cgroup_attach_task, cgroup_create, and __css_get. It is not necessary to set the bit in cgroup_fork, as the task is either in the root cgroup, in which can never be released, or the task it was forked from already set the bit in croup_attach_task.

2010-12-13PM: Wait for completion of the parent resume before resumingBenoit Goby
If the parent device is in the DPM_RESUMING state, resume might get called before the parent's resume has completed, because dpm_wait won't get called.

2010-12-11USB: gadget: acm,rndis: IAD class, subclass & prot should match 1st ifaceJohn Michelau
Microsoft recommends that the class and subclass fields of an IAD match the same fields from the first interface in the collection that the IAD is grouping. In practice, we are also finding that the protocol fields should also match. Without this change, the default Microsoft composite driver may not group interfaces properly, which is what allows child function drivers with IAD's to load correctly.

2010-12-11USB: gadget: android Fix gadget descriptor compliance for IAD'sJohn Michelau
USB-IF core team mandates that composite devices containing IAD's must use bDeviceClass=0xEF, bDeviceSubClass=0x02, & bDeviceProtocol=0x01 instead of the usual 0x00 in all fields. This is not a problem currently on Linux hosts, but it is a problem when connecting to Windows hosts. Without this change the default Microsoft composite driver will not group interfaces properly, which is what allows child function drivers with IAD's to load correctly.

2010-12-01fuse: fix attributes after open(O_TRUNC)Ken Sumrall
The attribute cache for a file was not being cleared when a file is opened with O_TRUNC. If the filesystem's open operation truncates the file ("atomic_o_trunc" feature flag is set) then the kernel should invalidate the cached st_mtime and st_ctime attributes. Also i_size should be explicitly be set to zero as it is used sometimes without refreshing the cache. Signed-off-by: Ken Sumrall <ksumrall@android.com> Cc: Anfei <anfei.zhou@gmail.com> Cc: "Anand V.

2010-12-01cpufreq: interactive: New 'interactive' governorMike Chan
This governor is designed for latency-sensitive workloads, such as interactive user interfaces. The interactive governor aims to be significantly more responsive to ramp CPU quickly up when CPU-intensive activity begins. Existing governors sample CPU load at a particular rate, typically every X ms. This can lead to under-powering UI threads for the period of time during which the user begins interacting with a previously-idle system until the next sample period happens. The 'interactive' governor uses a different approach. Instead of sampling the CPU at a specified rate, the governor will check whether to scale the CPU frequency up soon after coming out of idle. When the CPU comes out of idle, a timer is configured to fire within 1-2 ticks. If the CPU is very busy from exiting idle to when the timer fires then we assume the CPU is underpowered and ramp to MAX speed. If the CPU was not sufficiently busy to immediately ramp to MAX speed, then the governor evaluates the CPU load since the last speed adjustment, choosing the highest value between that longer-term load or the short-term load since idle exit to determine the CPU speed to ramp to. A realtime thread is used for scaling up, giving the remaining tasks the CPU performance benefit, unlike existing governors which are more likely to schedule rampup work to occur after your performance starved tasks have completed. The tuneables for this governor are: /sys/devices/system/cpu/cpufreq/interactive/min_sample_time: The minimum amount of time to spend at the current frequency before ramping down. This is to ensure that the governor has seen enough historic CPU load data to determine the appropriate workload. Default is 80000 uS. /sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load The CPU load at which to ramp to max speed. Default is 85.

2010-11-10Bluetooth: Add BT_POWER L2CAP socket option.Jaikumar Ganesh
Add BT_POWER socket option used to control the power characteristics of the underlying ACL link. When the remote end has put the link in sniff mode and the host stack wants to send data we need need to explicitly exit sniff mode to work well with certain devices (For example, A2DP on Plantronics Voyager 855). However, this causes problems with HID devices. Hence, moving into active mode when sending data, irrespective of who set the sniff mode has been made as a socket option. By default, we will move into active mode. HID devices can set the L2CAP socket option to prevent this from happening. Currently, this has been implemented for L2CAP sockets. This has been tested with incoming and outgoing L2CAP sockets for HID and A2DP. Based on discussions on linux-bluetooth and patches submitted by Andrei Emeltchenko.

2010-10-29ext4: fix kernel oops if the journal superblock has a non-zero j_errnoTheodore Ts'o
Commit 84061e0 fixed an accounting bug only to introduce the possibility of a kernel OOPS if the journal has a non-zero j_errno field indicating that the file system had detected a fs inconsistency. After the journal replay, if the journal superblock indicates that the file system has an error, this indication is transfered to the file system and then ext4_commit_super() is called to write this to the disk. But since the percpu counters are now initialized after the journal replay, the call to ext4_commit_super() will cause a kernel oops since it needs to use the percpu counters the ext4 superblock structure. The fix is to skip setting the ext4 free block and free inode fields if the percpu counter has not been set. Thanks to Ken Sumrall for reporting and analyzing the root causes of this bug.

Do this even if host->clock already equals zero, because the SDHCI driver may set that value (without calling the host op) to force an update at the next (non-zero-speed) call.
