Pull renameat2 system call from Miklos Szeredi:
"This adds a new syscall, renameat2(), which is the same as renameat()
but with a flags argument.The purpose of extending rename is to add cross-rename, a symmetric
variant of rename, which exchanges the two files. This allows
interesting things, which were not possible before, for example
atomically replacing a directory tree with a symlink, etc... This
also allows overlayfs and friends to operate on whiteouts atomically.Andy Lutomirski also suggested a "noreplace" flag, which disables the
overwriting behavior of rename.These two flags, RENAME_EXCHANGE and RENAME_NOREPLACE are only
implemented for ext4 as an example and for testing"* 'cross-rename' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs:

"The main set of series of patches for media subsystem, including:
- document RC sysfs class
- added an API to setup scancode to allow waking up systems using the
Remote Controller
- add API for SDR devices. Drivers are still on staging
- some API improvements for getting EDID data from media
inputs/outputs
- new DVB frontend driver for drx-j (ATSC)
- one driver (it913x/it9137) got removed, in favor of an improvement
on another driver (af9035)
- added a skeleton V4L2 PCI driver at documentation

reused.
- added a new SDR driver (rtl2832u_sdr)
- added a new tuner driver (msi001)
- several improvements at em28xx driver to fix PM support, device
removal and to split the V4L2 specific bits into a separate
sub-driver
- one driver got converted to videobuf2 (s2255drv)
- the e4000 tuner driver now follows an improved binding model
- some fixes at V4L2 compat32 code

- some cleanups at V4L2 API documentation
- usual driver enhancements, new board additions and misc fixups"[ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce
indentation in of_graph_get_next_endpoint").The of_graph_get_next_endpoint() function was moved and renamed by
commit fd9fdb78a9bf ("[media] of: move graph helpers from
drivers/media/v4l2-core to drivers/of"). It was originally called
v4l2_of_get_next_endpoint() and lived in the file
drivers/media/v4l2-core/v4l2-of.c.In that original location, it was then fixed to support empty port
nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port
nodes"), and that commit clashes badly with the dropped "Reduce
intendation" commit. I had to choose one or the other, and decided
that the "Support empty port nodes" commit was more important ]* 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (426 commits)

Pull bulk of gpio updates from Linus Walleij:
"A pretty big chunk of changes this time, but it has all been on
rotation in linux-next and had some testing. Of course there will be
some amount of fixes on top...- Merged in a branch of irqchip changes from Thomas Gleixner: we need
to have new callbacks from the irqchip to determine if the GPIO
line will be eligible for IRQs, and this callback must be able to
say "no". After some thinking I got the branch from tglx and have
switched all current users over to use this.- Based on tglx patches, we have added some generic irqchip helpers
in the gpiolib core. These will help centralize code when GPIO
drivers have simple chained/cascaded IRQs. Drivers will still
define their irqchip vtables, but the gpiolib core will take care
of irqdomain set-up, mapping from local offsets to Linux irqs, and
reserve resources by marking the GPIO lines for IRQs.- Initially the PL061 and Nomadik GPIO/pin control drivers have been
switched over to use the new gpiochip-to-irqchip infrastructure
with more drivers expected for the next kernel cycle. The
factoring of just two drivers still makes it worth it so it is
already a win.- A new driver for the Synopsys DesignWare APB GPIO block.
- Modify the DaVinci GPIO driver to be reusable also for the new TI
Keystone architecture.- A new driver for the LSI ZEVIO SoCs.
- Delete the obsolte tnetv107x driver.
- Some incremental work on GPIO descriptors: have
gpiod_direction_output() use a logical level, respecting assertion
polarity through ACTIVE_LOW flags, adding gpiod_direction_output_raw()
for the case where you want to set that very value. Add
gpiochip_get_desc() to fetch a GPIO descriptor from a specific
offset on a certain chip inside driver code.- Switch ACPI GPIO code over to using gpiochip_get_desc() and get rid
of gpio_to_desc().- The ACPI GPIO event handling code has been reworked after
encountering an actual real life implementation.- Support for ACPI GPIO operation regions.
- Generic GPIO chips can now be assigned labels/names from platform
data.- We now clamp values returned from GPIO drivers to the boolean [0,1]
range.- Some improved documentation on how to use the polarity flag was
added.- a large slew of incremental driver updates and non-critical fixes.

Add code to check sizes of on-disk data of metadata files such as inode

With this ioctl the segment usage entries in the SUFILE can be updated
from userspace.This is useful, because it allows the userspace GC to modify and update
segment usage entries for specific segments, which enables it to avoid
unnecessary write operations.If a segment needs to be cleaned, but there is no or very little
reclaimable space in it, the cleaning operation basically degrades to a
useless moving operation. In the end the only thing that changes is the
location of the data and a timestamp in the segment usage information.
With this ioctl the GC can skip the cleaning and update the segment
usage entries directly instead.This is basically a shortcut to cleaning the segment. It is still
necessary to read the segment summary information, but the writing of
the live blocks can be skipped if it's not worth it.[konishi.ryusuke@lab.ntt.co.jp: add description of NILFS_IOCTL_SET_SUINFO ioctl]
