      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.

        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"

      fs: return EPERM on immutable inode · 337684a1
      Eryu Guan 提交于
      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.

      Merge tag 'xfs-rmap-for-linus-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
      
      Pull more xfs updates from Dave Chinner:
       "This is the second part of the XFS updates for this merge cycle, and
        contains the new reverse block mapping feature for XFS.
      
        Reverse mapping allows us to track the owner of a specific block on
        disk precisely.  It is implemented as a set of btrees (one per
        allocation group) that track the owners of allocated extents.
        Effectively it is a "used space tree" that is updated when we allocate
        or free extents.  i.e. it is coherent with the free space btrees we
        already maintain and never overlaps with them.
      
        This reverse mapping infrastructure is the building block of several
        upcoming features - reflink, copy-on-write data, dedupe, online
        metadata and data scrubbing, highly accurate bad sector/data loss
        reporting to users, and significantly improved reconstruction of
        damaged and corrupted filesystems.  There's a lot of new stuff coming
        along in the next couple of cycles,a nd it all builds in the rmap
        infrastructure.
      
        As such, it's a huge chunk of new code with new on-disk format
        features and internal infrastructure.  It warns at mount time as an
        experimental feature and that it may eat data (as we do with all new
        on-disk features until they stabilise).  We have not released
        userspace suport for it yet - userspace support currently requires
        download from Darrick's xfsprogs repo and build from source, so the
        access to this feature is really developer/tester only at this point.
        Initial userspace support will be released at the same time kernel
        with this code in it is released.
      
        The new rmap enabled code regresses 3 xfstests - all are ENOSPC
        related corner cases, one of which Darrick posted a fix for a few
        hours ago.  The other two are fixed by infrastructure that is part of
        the upcoming reflink patchset.  This new ENOSPC infrastructure
        requires a on-disk format tweak required to keep mount times in
        check - we need to keep an on-disk count of allocated rmapbt blocks so
        we don't have to scan the entire btrees at mount time to count them.
      
        This is currently being tested and will be part of the fixes sent in
        the next week or two so users will not be exposed to this change"
