enabling
Consider the following v2 hierarchy.
P0 (+memory) --- P1 (-memory) --- A
\- B
P0 has memory enabled in its subtree_control while P1 doesn't. If
both A and B contain processes, they would belong to the memory css of
P1. Now if memory is enabled on P1's subtree_control, memory csses
should be created on both A and B and A's processes should be moved to
the former and B's processes the latter. IOW, enabling controllers
can cause atomic migrations into different csses.
The core cgroup migration logic has been updated accordingly but the
controller migration methods haven't and still assume that all tasks
migrate to a single target css; furthermore, the methods were fed the
css in which subtree_control was updated which is the parent of the
target csses. pids controller depends on the migration methods to
move charges and this made the controller attribute charges to the
wrong csses often triggering the following warning by driving a
counter negative.

This patch fixes the bug by removing @css parameter from the three
migration methods, ->can_attach, ->cancel_attach() and ->attach() and
updating cgroup_taskset iteration helpers also return the destination
css in addition to the task being migrated. All controllers are
updated accordingly.
* Controllers which don't care whether there are one or multiple
target csses can be converted trivially. cpu, io, freezer, perf,
netclassid and netprio fall in this category.
* cpuset's current implementation assumes that there's single source
and destination and thus doesn't support v2 hierarchy already. The
only change made by this patchset is how that single destination css
is obtained.
* memory migration path already doesn't do anything on v2. How the
single destination css is obtained is updated and the prep stage of
mem_cgroup_can_attach() is reordered to accomodate the change.
* pids is the only controller which was affected by this bug. It now
correctly handles multi-destination migrations and no longer causes
counter underflow from incorrect accounting.

For cpufreq drivers which use setpolicy interface, after offline->online
the policy is set to default. This can be reproduced by setting the
default policy of intel_pstate or longrun to ondemand and then change to
"performance". After offline and online, the setpolicy will be called with
the policy=ondemand.
For drivers using governors this condition is handled by storing
last_governor, during offline and restoring during online. The same should
be done for drivers using setpolicy interface. Storing last_policy during
offline and restoring during online.

Dmitry provided a syzkaller (http://github.com/google/syzkaller)
triggering a fault in sock_wake_async() when async IO is requested.
Said program stressed af_unix sockets, but the issue is generic
and should be addressed in core networking stack.
The problem is that by the time sock_wake_async() is called,
we should not access the @flags field of 'struct socket',
as the inode containing this socket might be freed without
further notice, and without RCU grace period.
We already maintain an RCU protected structure, "struct socket_wq"
so moving SOCKWQ_ASYNC_NOSPACE & SOCKWQ_ASYNC_WAITDATA into it
is the safe route.
It also reduces number of cache lines needing dirtying, so might
provide a performance improvement anyway.
In followup patches, we might move remaining flags (SOCK_NOSPACE,
SOCK_PASSCRED, SOCK_PASSSEC) to save 8 bytes and let 'struct socket'
being mostly read and let it being shared between cpus.

This patch is a cleanup to make following patch easier to
review.
Goal is to move SOCK_ASYNC_NOSPACE and SOCK_ASYNC_WAITDATA
from (struct socket)->flags to a (struct socket_wq)->flags
to benefit from RCU protection in sock_wake_async()
To ease backports, we rename both constants.
Two new helpers, sk_set_bit(int nr, struct sock *sk)
and sk_clear_bit(int net, struct sock *sk) are added so that
following patch can change their implementation.

Add a copy_file_range() system call for offloading copies between
regular files.
This gives an interface to underlying layers of the storage stack which
can copy without reading and writing all the data. There are a few
candidates that should support copy offloading in the nearer term:
- btrfs shares extent references with its clone ioctl
- NFS has patches to add a COPY command which copies on the server
- SCSI has a family of XCOPY commands which copy in the device
This system call avoids the complexity of also accelerating the creation
of the destination file by operating on an existing destination file
descriptor, not a path.
Currently the high level vfs entry point limits copy offloading to files
on the same mount and super (and not in the same file). This can be
relaxed if we get implementations which can copy between file systems
safely.

Jonathan writes:
First set of new device support, features and cleanups for IIO in the 4.5 cycle
Usual mixed bag, but the big item perhaps in this series is the DMA buffer
support added by Lars-Peter Clausen. It's been in the works for a long time
and it will be interesting to see what hardware support shows up now that
this is available.
New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
Also associated minor changes.
- Set the device buffer watermark based on the minimum watermark for all
attached buffers rather than just the 'primary' one.
- iio_buffer_init - only set the watermark default if one hasn't already
been provided. This allows simple support for devices with a fixed
watermark.
- read only attribute for watermark on fixed watermark devices.
- add explicit buffer enable/disable callbacks to allow the buffer to
do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.
New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc
New driver features
* mma8452
- support either of the available interrupt pins to cope with the case
where board layout has lead to a particular one being connected.
Staging graduation
* Dummy driver
- this driver acts as both an example and a test device for those with
out hardware to develop userspace code against.
Cleanups and minor bits and bobs.
* treewide
- Sort out the ordering of iio_device_register/unregister vs runtime
pm function calls so that it's all nice and consistent and not race
prone.
- Check sscanf return values. None of the cases will actually happen as
the strings are supplied internally, but best to be consistent on this.
* ad7780
- switch over to the gpio descriptor interface and remove the now unused
platform data which gets rid of a header entirely.
* ad7793
- drop a pointless else statement.
* at91_adc
- Swap kmalloc_array in for a kmalloc doing the same job.
* dummy
- get rid of some commented out lines that snuck in during the move of
the driver.
* lm3533-als
- Print an error message on provision of an invalid resistance.
* mcp320x
- Add compatible strings with vendor prefix and deprecate those with
no vendor prefix.
* mxs-lradc
- Use BIT macro in various places rather than shifted ones.
* pa12203001
- Power off the chip if the registration fails.
* pulsedlight-lidar-lite
- add runtime PM support.
* xilinx XADC
- constify an iio_buffer_setup_ops structure.

this change the payload was optional.
This fixes PPPoE connections which do not have a "Service" or

widely used in real-world setups). Those are currently failing with the
following message: "pppd: packet size is too short (24 <= 24)"

When a cloned request is retried on other queues it always needs

Otherwise the calculations for nr_phys_segments might be wrong,
leading to a crash in scsi_init_sgtable().
To clarify this the patch renames blk_rq_check_limits()
to blk_cloned_rq_check_limits() and removes the symbol
export, as the new function should only be used for
cloned requests and never exported.

Pull ARM SoC fixes from Arnd Bergmann:
"There is a small backlog of at91 patches here, the most significant is
the addition of some sama5d2 Xplained nodes that were waiting on an
MFD include file to get merged through another tree.
We normally try to sort those out before the merge window opens, but
the maintainer wasn't aware of that here and I decided to merge the
changes this time as an exception.
On OMAP a series of audio changes for dra7 missed the merge window but
turned out to be necessary to fix a boot time imprecise external abort
error and to get audio working.
The other changes are the usual simple changes, here is a list sorted
by platform:
at91:
removal of a useless defconfig option
removal of some legacy DT pieces
use of the proper watchdog compatible string
update of the MAINTAINERS entries for some Atmel drivers
drivers/scpi:
hide get_scpi_ops in module from built-in code
imx:

Pull arm64 fixes from Catalin Marinas:
- Build fix when !CONFIG_UID16 (the patch is touching generic files but
it only affects arm64 builds; submitted by Arnd Bergmann)
- EFI fixes to deal with early_memremap() returning NULL and correctly
mapping run-time regions
- Fix CPUID register extraction of unsigned fields (not to be
sign-extended)
- ASID allocator fix to deal with long-running tasks over multiple
generation roll-overs
- Revert support for marking page ranges as contiguous PTEs (it leads
to TLB conflicts and requires additional non-trivial kernel changes)
- Proper early_alloc() failure check
- Disable KASan for 48-bit VA and 16KB page configuration (the pgd is
larger than the KASan shadow memory)
- Update the fault_info table (original descriptions based on early
engineering spec)

Commit 4f258a46346c ("sd: Fix maximum I/O size for BLOCK_PC requests")
had the unfortunate side-effect of removing an implicit clamp to
BLK_DEF_MAX_SECTORS for REQ_TYPE_FS requests in the block layer
code. This caused problems for some SMR drives.
Debugging this issue revealed a few problems with the existing
infrastructure since the block layer didn't know how to deal with
device-imposed limits, only limits set by the I/O controller.
- Introduce a new queue limit, max_dev_sectors, which is used by the
ULD to signal the maximum sectors for a REQ_TYPE_FS request.
- Ensure that max_dev_sectors is correctly stacked and taken into
account when overriding max_sectors through sysfs.
- Rework sd_read_block_limits() so it saves the max_xfer and opt_xfer
values for later processing.
- In sd_revalidate() set the queue's max_dev_sectors based on the
MAXIMUM TRANSFER LENGTH value in the Block Limits VPD. If this value
is not reported, fall back to a cap based on the CDB TRANSFER LENGTH
field size.
- In sd_revalidate(), use OPTIMAL TRANSFER LENGTH from the Block Limits
VPD--if reported and sane--to signal the preferred device transfer
size for FS requests. Otherwise use BLK_DEF_MAX_SECTORS.
- blk_limits_max_hw_sectors() is no longer used and can be removed.

Linux 4.4-rc2 is backmerged from the keystone fixes.
|
|
We cache all hotpath members of a clocksource in the time keeper
core. So there is no requirement in general to cache line align struct
clocksource. Remove the enforces alignment.
That allows users which need to wrap struct clocksource into their own
struct to align the struct without getting extra padding.
