      Merge branch 'for-linus' of git://git.kernel.dk/linux-block · 857953d7
      Linus Torvalds authored 
      Pull more block fixes from Jens Axboe:
 "As mentioned in the pull the other day, a few more fixes for this
  round, all related to the bio op changes in this series.

  Two fixes, and then a cleanup, renaming bio->bi_rw to bio->bi_opf.  I
  wanted to do that change right after or right before -rc1, so that
  risk of conflict was reduced.  I just rebased the series on top of
  current master, and no new ->bi_rw usage has snuck in"

* 'for-linus' of git://git.kernel.dk/linux-block:
  block: rename bio bi_rw to bi_opf
  target: iblock_execute_sync_cache() should use bio_set_op_attrs()

      Pull drm zpos property support from Dave Airlie:
 "This tree was waiting on some media stuff I hadn't had time to get a
  stable branchpoint off, so I just waited until it was all in your tree
  first.

  It's been around a bit on the list and shouldn't affect anything
  outside adding the generic API and moving some ARM drivers to using
  it"

      block: rename bio bi_rw to bi_opf · 1eff9d32
      Jens Axboe authored 
      Since commit 63a4cc24, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

No intended functional changes in this commit.

      The original commit missed this function, it needs to mark it a
write flush.

      block/mm: make bdev_ops->rw_page() take a bool for read/write · c11f0c0b
      Jens Axboe authored 
      Commit abf54548 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.

Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

      Merge tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc · e9d488c3
      Linus Torvalds authored 
      Pull binfmt_misc update from James Bottomley:
 "This update is to allow architecture emulation containers to function
  such that the emulation binary can be housed outside the container
  itself.  The container and fs parts both have acks from relevant
  experts.

  To use the new feature you have to add an F option to your binfmt_misc
  configuration"

From the docs:
 "The usual behaviour of binfmt_misc is to spawn the binary lazily when
  the misc format file is invoked.  However, this doesn't work very well
  in the face of mount namespaces and changeroots, so the F mode opens
  the binary as soon as the emulation is installed and uses the opened
  image to spawn the emulator, meaning it is always available once
  installed, regardless of how the environment changes"

* tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc:
  binfmt_misc: add F option description to documentation
  binfmt_misc: add persistent opened binary handler for containers
  fs: add filp_clone_open API

      fs: return EPERM on immutable inode · 337684a1
      Eryu Guan authored 
      In most cases, EPERM is returned on immutable inode, and there're only a
few places returning EACCES. I noticed this when running LTP on
overlayfs, setxattr03 failed due to unexpected EACCES on immutable
inode.

So converting all EACCES to EPERM on immutable inode.
