vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03+00:00

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

   DVB subsystem too

 - Digital TV core memory mapped support interface

 - new sensor driver: ov7740

Merge tag 'staging-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here is the big Staging and IIO driver patches for 4.16-rc1.

  There is the normal amount of new IIO drivers added, like all
  releases.

  The networking IPX and the ncpfs filesystem are moved into the staging
  tree, as they are on their way out of the kernel due to lack of use
  anymore.

  The visorbus subsystem finall has started moving out of the staging
  tree to the "real" part of the kernel, and the most and fsl-mc
  codebases are almost ready to move out, that will probably happen for
  4.17-rc1 if all goes well.

  Other than that, there is a bunch of license header cleanups in the
  tree, along with the normal amount of coding style churn that we all
  know and love for this codebase. I also got frustrated at the
  Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting
  huge chunks of it that were never even being used.

  Full details of everything is in the shortlog.

  All of these patches have been in linux-next for a while with no
  reported issues"

Merge branch 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2018-01-31T01:58:07+00:00

Pull poll annotations from Al Viro:
 "This introduces a __bitwise type for POLL### bitmap, and propagates
  the annotations through the tree. Most of that stuff is as simple as
  'make ->poll() instances return __poll_t and do the same to local
  variables used to hold the future return value'.

  Some of the obvious brainos found in process are fixed (e.g. POLLIN
  misspelled as POLL_IN). At that point the amount of sparse warnings is
  low and most of them are for genuine bugs - e.g. ->poll() instance
  deciding to return -EINVAL instead of a bitmap. I hadn't touched those
  in this series - it's large enough as it is.

  Another problem it has caught was eventpoll() ABI mess; select.c and
  eventpoll.c assumed that corresponding POLL### and EPOLL### were
  equal. That's true for some, but not all of them - EPOLL### are
  arch-independent, but POLL### are not.

  The last commit in this series separates userland POLL### values from
  the (now arch-independent) kernel-side ones, converting between them
  in the few places where they are copied to/from userland. AFAICS, this
  is the least disruptive fix preserving poll(2) ABI and making epoll()
  work on all architectures.

  As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
  it will trigger only on what would've triggered EPOLLWRBAND on other
  architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
  at all on sparc. With this patch they should work consistently on all
  architectures"

media: v4l2-async: simplify v4l2_async_subdev structure

2017-12-29T12:14:28+00:00

The V4L2_ASYNC_MATCH_FWNODE match criteria requires just one
struct to be filled (struct fwnode_handle). The V4L2_ASYNC_MATCH_DEVNAME
match criteria requires just a device name.

So, it doesn't make sense to enclose those into structs,
as the criteria can go directly into the union.

That makes easier to document it, as we don't need to document
weird senseless structs.

At drivers, this makes even clearer about the match criteria.
