altera-ps-spi loads FPGA firmware over SPI, using the "passive serial"
interface on Altera Arria 10, Cyclone V or Stratix V FPGAs.
This is one of the simpler ways to set up an FPGA at runtime.
The signal interface is close to unidirectional SPI with lsb first.

Rename it to chip.h, as for other source/header pairs of the driver.
At the same time, ensure that relative header inclusions are separated

Add an API to get kernfs node from inode number. We will need this to
implement exportfs operations.
To make the API lock free, kernfs node is freed in RCU context. And we
depend on kernfs_node count/ino number to filter stale kernfs nodes.

blkcg_bio_issue_check() already gets blkcg for a BIO.
bio_associate_blkcg() uses a percpu refcounter, so it's a very cheap
operation. There is no point we don't attach the cgroup info into bio at
blkcg_bio_issue_check. This also makes blktrace outputs correct cgroup
info.

Currently cfq/bfq/blk-throttle output cgroup info in trace in their own
way. Now we have standard blktrace API for this, so convert them to use
it.
Note, this changes the behavior a little bit. cgroup info isn't output
by default, we only do this with 'blk_cgroup' option enabled

bio_free isn't a good place to free cgroup/integrity info. There are a
lot of cases bio is allocated in special way (for example, in stack) and
never gets called by bio_put hence bio_free, we are leaking memory. This
patch moves the free to bio endio, which should be called anywa

By default we output cgroup id in blktrace. This adds an option to
display cgroup path. Since get cgroup path is a relativly heavy
operation, we don't enable it by default.
with the option enabled, blktrace will output something like this:

Set i_generation for kernfs inode. This is required to implement exportfs
operations.
Note, the generation is 32-bit, so it's possible the generation wraps up
and we find stale files. The possiblity is low, since fhandle matches
both inode number and generation. In most fs, the

Hi Thierry,
What is the gain of introducing multiplanar API for this hardware?
AFAIR all the HW implementations store the data in a single contiguous
memory region and use suitable padding between planes.

We noticed in testing that affined workloads do not provide consistent
performance under certain circumstances. To isolate the issue, we began
testing with a representative CPU workload. In some cases the CPU workload
results would vary by a large percentage from run to run. We used JTAG and
schedu
If load_balance() fails to migrate any tasks because all tasks were
affined, load_balance() removes the source cpu from consideration and
attempts to redo and balance among the new subset of cpus.
There is a bug in this code path where the algorithm considers all active
cpus in the system (minus t
The group_imbalance path in calculate_imbalance() made sense when it was
added back in 2007 with commit 908a7c1b9b80 ("sched: fix improper load
balance across sched domain") because busiest->load_per_task factored into
the amount of imbalance that was calculated. That is not the case today.
