2011-10-11staging:iio:dac:ad5638: Fix channel addressLars-Peter Clausen
Commit c6fc806247 ("staging:iio: ABI rework - add in_ or out_ prefix to channnels") added the AD5868_CHANNEL macro to simplify channel initialization. Unfortunately the macro hardcodes the channel's address to AD5686_ADDR_DAC0. As a result writing to any of the channels will change the value of the first channel. This patch fixes the issue by calculating the channel address based on the channel number.

2011-10-11Btrfs: make sure not to defrag extents past i_sizeChris Mason
The btrfs file defrag code will loop through the extents and force COW on them. But there is a concurrent truncate in the middle of the defrag, it might end up defragging the same range over and over again. The problem is that writepage won't go through and do anything on pages past i_size, so the cow won't happen, so the file will appear to still be fragmented. defrag will end up hitting the same extents again and again. In the worst case, the truncate can actually live lock with the defrag because the defrag keeps creating new ordered extents which the truncate code keeps waiting on. The fix here is to make defrag check for i_size inside the main loop, instead of just once before the looping starts. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2011-10-11tracing: Do not allocate buffer for trace_markerSteven Rostedt
When doing intense tracing, the kmalloc inside trace_marker can introduce side effects to what is being traced. As trace_marker() is used by userspace to inject data into the kernel ring buffer, it needs to do so with the least amount of intrusion to the operations of the kernel or the user space application. As the ring buffer is designed to write directly into the buffer without the need to make a temporary buffer, and userspace already went through the hassle of knowing how big the write will be, we can simply pin the userspace pages and write the data directly into the buffer. This improves the impact of tracing via trace_marker tremendously! Thanks to Peter Zijlstra and Thomas Gleixner for pointing out the use of get_user_pages_fast() and kmap_atomic().

2011-10-11tracing: Warn on output if the function tracer was found corruptedSteven Rostedt
As the function tracer is very intrusive, lots of self checks are performed on the tracer and if something is found to be strange it will shut itself down keeping it from corrupting the rest of the kernel. This shutdown may still allow functions to be traced, as the tracing only stops new modifications from happening. Trying to stop the function tracer itself can cause more harm as it requires code modification. Although a WARN_ON() is executed, a user may not notice it. To help the user see that something isn't right with the tracing of the system a big warning is added to the output of the tracer that lets the user know that their data may be incomplete.

2011-10-11md: add proper write-congestion reporting to RAID1 and RAID10.NeilBrown
RAID1 and RAID10 handle write requests by queuing them for handling by a separate thread. This is because when a write-intent-bitmap is active we might need to update the bitmap first, so it is good to queue a lot of writes, then do one big bitmap update for them all. However writeback request devices to appear to be congested after a while so it can make some guesstimate of throughput. The infinite queue defeats that (note that RAID5 has already has a finite queue so it doesn't suffer from this problem). So impose a limit on the number of pending write requests. By default it is 1024 which seems to be generally suitable. Make it configurable via module option just in case someone finds a regression. Signed-off-by: NeilBrown <neilb@suse.de>
